Provide tags and a correct Python 3 solution for this coding contest problem. Beroffice text editor has a wide range of features that help working with text. One of the features is an automatic search for typos and suggestions of how to fix them. Beroffice works only with small English letters (i.e. with 26 letters from a to z). Beroffice thinks that a word is typed with a typo if there are three or more consonants in a row in the word. The only exception is that if the block of consonants has all letters the same, then this block (even if its length is greater than three) is not considered a typo. Formally, a word is typed with a typo if there is a block of not less that three consonants in a row, and there are at least two different letters in this block. For example: * the following words have typos: "hellno", "hackcerrs" and "backtothefutttture"; * the following words don't have typos: "helllllooooo", "tobeornottobe" and "oooooo". When Beroffice editor finds a word with a typo, it inserts as little as possible number of spaces in this word (dividing it into several words) in such a way that each of the resulting words is typed without any typos. Implement this feature of Beroffice editor. Consider the following letters as the only vowels: 'a', 'e', 'i', 'o' and 'u'. All the other letters are consonants in this problem. Input The only line contains a non-empty word consisting of small English letters. The length of the word is between 1 and 3000 letters. Output Print the given word without any changes if there are no typos. If there is at least one typo in the word, insert the minimum number of spaces into the word so that each of the resulting words doesn't have any typos. If there are multiple solutions, print any of them. Examples Input hellno Output hell no Input abacaba Output abacaba Input asdfasdf Output asd fasd f Tags: dp, greedy, implementation Correct Solution: ``` s = input() d = ['a', 'e', 'i', 'o', 'u'] st = [] for i in range(len(s)): if s[i] in d: st = [] print(s[i], end="") continue st.append(s[i]) if st == [s[i], s[i], s[i]]: st = st[1:] print(s[i], end='') elif len(st) == 3: st = [s[i]] print(" " + s[i], end="") else: print(s[i], end='') ```

Provide tags and a correct Python 3 solution for this coding contest problem. Beroffice text editor has a wide range of features that help working with text. One of the features is an automatic search for typos and suggestions of how to fix them. Beroffice works only with small English letters (i.e. with 26 letters from a to z). Beroffice thinks that a word is typed with a typo if there are three or more consonants in a row in the word. The only exception is that if the block of consonants has all letters the same, then this block (even if its length is greater than three) is not considered a typo. Formally, a word is typed with a typo if there is a block of not less that three consonants in a row, and there are at least two different letters in this block. For example: * the following words have typos: "hellno", "hackcerrs" and "backtothefutttture"; * the following words don't have typos: "helllllooooo", "tobeornottobe" and "oooooo". When Beroffice editor finds a word with a typo, it inserts as little as possible number of spaces in this word (dividing it into several words) in such a way that each of the resulting words is typed without any typos. Implement this feature of Beroffice editor. Consider the following letters as the only vowels: 'a', 'e', 'i', 'o' and 'u'. All the other letters are consonants in this problem. Input The only line contains a non-empty word consisting of small English letters. The length of the word is between 1 and 3000 letters. Output Print the given word without any changes if there are no typos. If there is at least one typo in the word, insert the minimum number of spaces into the word so that each of the resulting words doesn't have any typos. If there are multiple solutions, print any of them. Examples Input hellno Output hell no Input abacaba Output abacaba Input asdfasdf Output asd fasd f Tags: dp, greedy, implementation Correct Solution: ``` s=input() l='aeiou' i=2 while(i<len(s)): if(s[i]!=s[i-1] or s[i]!=s[i-2] or s[i-1]!=s[i-2]) and (s[i] not in l) and (s[i-1] not in l) and (s[i-2] not in l) : s=s[:i]+" "+s[i:] i+=2 i+=1 print(s) ```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Beroffice text editor has a wide range of features that help working with text. One of the features is an automatic search for typos and suggestions of how to fix them. Beroffice works only with small English letters (i.e. with 26 letters from a to z). Beroffice thinks that a word is typed with a typo if there are three or more consonants in a row in the word. The only exception is that if the block of consonants has all letters the same, then this block (even if its length is greater than three) is not considered a typo. Formally, a word is typed with a typo if there is a block of not less that three consonants in a row, and there are at least two different letters in this block. For example: * the following words have typos: "hellno", "hackcerrs" and "backtothefutttture"; * the following words don't have typos: "helllllooooo", "tobeornottobe" and "oooooo". When Beroffice editor finds a word with a typo, it inserts as little as possible number of spaces in this word (dividing it into several words) in such a way that each of the resulting words is typed without any typos. Implement this feature of Beroffice editor. Consider the following letters as the only vowels: 'a', 'e', 'i', 'o' and 'u'. All the other letters are consonants in this problem. Input The only line contains a non-empty word consisting of small English letters. The length of the word is between 1 and 3000 letters. Output Print the given word without any changes if there are no typos. If there is at least one typo in the word, insert the minimum number of spaces into the word so that each of the resulting words doesn't have any typos. If there are multiple solutions, print any of them.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Beroffice text editor has a wide range of features that help working with text. One of the features is an automatic search for typos and suggestions of how to fix them. Beroffice works only with small English letters (i.e. with 26 letters from a to z). Beroffice thinks that a word is typed with a typo if there are three or more consonants in a row in the word. The only exception is that if the block of consonants has all letters the same, then this block (even if its length is greater than three) is not considered a typo. Formally, a word is typed with a typo if there is a block of not less that three consonants in a row, and there are at least two different letters in this block. For example: * the following words have typos: "hellno", "hackcerrs" and "backtothefutttture"; * the following words don't have typos: "helllllooooo", "tobeornottobe" and "oooooo". When Beroffice editor finds a word with a typo, it inserts as little as possible number of spaces in this word (dividing it into several words) in such a way that each of the resulting words is typed without any typos. Implement this feature of Beroffice editor. Consider the following letters as the only vowels: 'a', 'e', 'i', 'o' and 'u'. All the other letters are consonants in this problem. Input The only line contains a non-empty word consisting of small English letters. The length of the word is between 1 and 3000 letters. Output Print the given word without any changes if there are no typos. If there is at least one typo in the word, insert the minimum number of spaces into the word so that each of the resulting words doesn't have any typos. If there are multiple solutions, print any of them. Examples Input hellno Output hell no Input abacaba Output abacaba Input asdfasdf Output asd fasd f Submitted Solution: ``` a = input() x =2 while x<len(a): if a[x]!= 'a' and a[x]!= 'e' and a[x]!= 'i' and a[x]!= 'o' and a[x]!= 'u' and a[x]!= ' ': if a[x-1]!= 'a' and a[x-1]!= 'e' and a[x-1]!= 'i' and a[x-1]!= 'o' and a[x-1]!= 'u' and a[x-1]!= ' ' and a[x-2]!= 'a' and a[x-2]!= 'e' and a[x-2]!= 'i' and a[x-2]!= 'o' and a[x-2]!= 'u' and a[x-2]!= ' ': if a[x-2]!=a[x] or a[x]!=a[x-1]: a = a[0:x]+' '+a[x:] x+=1 x+=1 print(a) ``` Yes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Beroffice text editor has a wide range of features that help working with text. One of the features is an automatic search for typos and suggestions of how to fix them. Beroffice works only with small English letters (i.e. with 26 letters from a to z). Beroffice thinks that a word is typed with a typo if there are three or more consonants in a row in the word. The only exception is that if the block of consonants has all letters the same, then this block (even if its length is greater than three) is not considered a typo. Formally, a word is typed with a typo if there is a block of not less that three consonants in a row, and there are at least two different letters in this block. For example: * the following words have typos: "hellno", "hackcerrs" and "backtothefutttture"; * the following words don't have typos: "helllllooooo", "tobeornottobe" and "oooooo". When Beroffice editor finds a word with a typo, it inserts as little as possible number of spaces in this word (dividing it into several words) in such a way that each of the resulting words is typed without any typos. Implement this feature of Beroffice editor. Consider the following letters as the only vowels: 'a', 'e', 'i', 'o' and 'u'. All the other letters are consonants in this problem. Input The only line contains a non-empty word consisting of small English letters. The length of the word is between 1 and 3000 letters. Output Print the given word without any changes if there are no typos. If there is at least one typo in the word, insert the minimum number of spaces into the word so that each of the resulting words doesn't have any typos. If there are multiple solutions, print any of them. Examples Input hellno Output hell no Input abacaba Output abacaba Input asdfasdf Output asd fasd f Submitted Solution: ``` def sogl(a): glas = ['u', 'a', 'i', 'e', 'o'] for letter in glas: if letter == a: return False return True def xor(a,b,c): j = 0 if a==b: j+=1 if a==c: j+=1 if j == 2: return False else: return True line = input() let = 0 for i in range(0, len(line)): #test1=sogl(line[i]) #test2 = let #test3 = xor(line[i], line[i-1], line[i-2]) if (sogl(line[i])) and (let<2): let += 1 print(line[i], end='') elif (sogl(line[i])) and (let==2) and (xor(line[i], line[i-1], line[i-2])): let = 1 print(' ',end='') print(line[i], end='') elif (sogl(line[i])) and (let==2) and not(xor(line[i], line[i-1], line[i-2])): print(line[i], end='') else: let = 0 print(line[i], end='') ``` Yes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Beroffice text editor has a wide range of features that help working with text. One of the features is an automatic search for typos and suggestions of how to fix them. Beroffice works only with small English letters (i.e. with 26 letters from a to z). Beroffice thinks that a word is typed with a typo if there are three or more consonants in a row in the word. The only exception is that if the block of consonants has all letters the same, then this block (even if its length is greater than three) is not considered a typo. Formally, a word is typed with a typo if there is a block of not less that three consonants in a row, and there are at least two different letters in this block. For example: * the following words have typos: "hellno", "hackcerrs" and "backtothefutttture"; * the following words don't have typos: "helllllooooo", "tobeornottobe" and "oooooo". When Beroffice editor finds a word with a typo, it inserts as little as possible number of spaces in this word (dividing it into several words) in such a way that each of the resulting words is typed without any typos. Implement this feature of Beroffice editor. Consider the following letters as the only vowels: 'a', 'e', 'i', 'o' and 'u'. All the other letters are consonants in this problem. Input The only line contains a non-empty word consisting of small English letters. The length of the word is between 1 and 3000 letters. Output Print the given word without any changes if there are no typos. If there is at least one typo in the word, insert the minimum number of spaces into the word so that each of the resulting words doesn't have any typos. If there are multiple solutions, print any of them. Examples Input hellno Output hell no Input abacaba Output abacaba Input asdfasdf Output asd fasd f Submitted Solution: ``` s = input() vows = ['a', 'e', 'u', 'i', 'o'] i = 0 s1 = '' while i < (len(s)-2): if s[i] not in vows and s[i+1] not in vows and s[i+2] not in vows: if s[i] != s[i+1] or s[i+1] != s[i+2]: s1+=s[i: i+2] + ' ' i+=2 else: s1+=s[i] i+=1 else: s1+=s[i] i+=1 s1+=s[i:] print (s1) ``` Yes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Beroffice text editor has a wide range of features that help working with text. One of the features is an automatic search for typos and suggestions of how to fix them. Beroffice works only with small English letters (i.e. with 26 letters from a to z). Beroffice thinks that a word is typed with a typo if there are three or more consonants in a row in the word. The only exception is that if the block of consonants has all letters the same, then this block (even if its length is greater than three) is not considered a typo. Formally, a word is typed with a typo if there is a block of not less that three consonants in a row, and there are at least two different letters in this block. For example: * the following words have typos: "hellno", "hackcerrs" and "backtothefutttture"; * the following words don't have typos: "helllllooooo", "tobeornottobe" and "oooooo". When Beroffice editor finds a word with a typo, it inserts as little as possible number of spaces in this word (dividing it into several words) in such a way that each of the resulting words is typed without any typos. Implement this feature of Beroffice editor. Consider the following letters as the only vowels: 'a', 'e', 'i', 'o' and 'u'. All the other letters are consonants in this problem. Input The only line contains a non-empty word consisting of small English letters. The length of the word is between 1 and 3000 letters. Output Print the given word without any changes if there are no typos. If there is at least one typo in the word, insert the minimum number of spaces into the word so that each of the resulting words doesn't have any typos. If there are multiple solutions, print any of them. Examples Input hellno Output hell no Input abacaba Output abacaba Input asdfasdf Output asd fasd f Submitted Solution: ``` # Задачка C # гласные vowels = 'aeiou' word = input() consonants = word[0] not in vowels duplicates = 0 result = '' term = word[0] for p, w in zip(word, word[1:]): if w not in vowels: consonants += 1 else: consonants = duplicates = 0 if consonants > 0: duplicates += p==w if consonants > 2 and duplicates != consonants-1: result += term + ' ' + w consonants = duplicates = 0 term = '' else: term += w result += term if result.startswith(' '): result == result[1:] print(result) ``` No

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Beroffice text editor has a wide range of features that help working with text. One of the features is an automatic search for typos and suggestions of how to fix them. Beroffice works only with small English letters (i.e. with 26 letters from a to z). Beroffice thinks that a word is typed with a typo if there are three or more consonants in a row in the word. The only exception is that if the block of consonants has all letters the same, then this block (even if its length is greater than three) is not considered a typo. Formally, a word is typed with a typo if there is a block of not less that three consonants in a row, and there are at least two different letters in this block. For example: * the following words have typos: "hellno", "hackcerrs" and "backtothefutttture"; * the following words don't have typos: "helllllooooo", "tobeornottobe" and "oooooo". When Beroffice editor finds a word with a typo, it inserts as little as possible number of spaces in this word (dividing it into several words) in such a way that each of the resulting words is typed without any typos. Implement this feature of Beroffice editor. Consider the following letters as the only vowels: 'a', 'e', 'i', 'o' and 'u'. All the other letters are consonants in this problem. Input The only line contains a non-empty word consisting of small English letters. The length of the word is between 1 and 3000 letters. Output Print the given word without any changes if there are no typos. If there is at least one typo in the word, insert the minimum number of spaces into the word so that each of the resulting words doesn't have any typos. If there are multiple solutions, print any of them. Examples Input hellno Output hell no Input abacaba Output abacaba Input asdfasdf Output asd fasd f Submitted Solution: ``` s = input() g = {'a', 'e', 'i', 'o', 'u'} l = 0 lc = "" for ch in s: if ch not in g and lc != ch: l+=1 else: l=0 if l>2 and lc != ch: print(" ", end="") l = 1 lc = ch print(ch, end="") ``` No

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Beroffice text editor has a wide range of features that help working with text. One of the features is an automatic search for typos and suggestions of how to fix them. Beroffice works only with small English letters (i.e. with 26 letters from a to z). Beroffice thinks that a word is typed with a typo if there are three or more consonants in a row in the word. The only exception is that if the block of consonants has all letters the same, then this block (even if its length is greater than three) is not considered a typo. Formally, a word is typed with a typo if there is a block of not less that three consonants in a row, and there are at least two different letters in this block. For example: * the following words have typos: "hellno", "hackcerrs" and "backtothefutttture"; * the following words don't have typos: "helllllooooo", "tobeornottobe" and "oooooo". When Beroffice editor finds a word with a typo, it inserts as little as possible number of spaces in this word (dividing it into several words) in such a way that each of the resulting words is typed without any typos. Implement this feature of Beroffice editor. Consider the following letters as the only vowels: 'a', 'e', 'i', 'o' and 'u'. All the other letters are consonants in this problem. Input The only line contains a non-empty word consisting of small English letters. The length of the word is between 1 and 3000 letters. Output Print the given word without any changes if there are no typos. If there is at least one typo in the word, insert the minimum number of spaces into the word so that each of the resulting words doesn't have any typos. If there are multiple solutions, print any of them. Examples Input hellno Output hell no Input abacaba Output abacaba Input asdfasdf Output asd fasd f Submitted Solution: ``` import re s = list(input()) #s = list("orfyaenanabsdfckumulsbolo") vowels = "aeiou" c = "" sections = [] for i in range(len(s)): if s[i] in vowels: sections.append(c) sections.append(s[i]) c = "" elif i == len(s) - 1: c += s[i] sections.append(c) else: c += s[i] new = [] for i in range(len(sections)): blurb = sections[i] length = len(blurb) if length >= 4 and length % 2 == 0: for j in range(length // 2): if j == (length // 2) - 1: new.append(blurb) else: new.append(blurb[:2] + " ") blurb = blurb[2:] elif length >= 4 and length % 2 != 0: for j in range(length // 2): if j == (length // 2) - 1: new.append(blurb) else: new.append(blurb[:2] + " ") blurb = blurb[2:] elif length >= 3: new.append(blurb[:2] + " ") new.append(blurb[2:]) else: new.append(blurb) t = "" new_s = t.join(new) print(new_s) ``` No

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Beroffice text editor has a wide range of features that help working with text. One of the features is an automatic search for typos and suggestions of how to fix them. Beroffice works only with small English letters (i.e. with 26 letters from a to z). Beroffice thinks that a word is typed with a typo if there are three or more consonants in a row in the word. The only exception is that if the block of consonants has all letters the same, then this block (even if its length is greater than three) is not considered a typo. Formally, a word is typed with a typo if there is a block of not less that three consonants in a row, and there are at least two different letters in this block. For example: * the following words have typos: "hellno", "hackcerrs" and "backtothefutttture"; * the following words don't have typos: "helllllooooo", "tobeornottobe" and "oooooo". When Beroffice editor finds a word with a typo, it inserts as little as possible number of spaces in this word (dividing it into several words) in such a way that each of the resulting words is typed without any typos. Implement this feature of Beroffice editor. Consider the following letters as the only vowels: 'a', 'e', 'i', 'o' and 'u'. All the other letters are consonants in this problem. Input The only line contains a non-empty word consisting of small English letters. The length of the word is between 1 and 3000 letters. Output Print the given word without any changes if there are no typos. If there is at least one typo in the word, insert the minimum number of spaces into the word so that each of the resulting words doesn't have any typos. If there are multiple solutions, print any of them. Examples Input hellno Output hell no Input abacaba Output abacaba Input asdfasdf Output asd fasd f Submitted Solution: ``` def Dif(string): if s.count(s[0]) != len(s): return True else: return False s = input() s1 = '' b = False for i in range(len(s)): if s[i] != 'a' and s[i] != 'e' and s[i] != 'i' and s[i] != 'o' and s[i] != 'u': s1 += s[i] if len(s1) > 2 and Dif(s1): b = True break else: s1 = '' if b: s1 = '' s2 = '' for i in range(len(s)): if s[i] == 'a' or s[i] == 'e' or s[i] == 'i' or s[i] == 'o' or s[i] == 'u': if len(s1) > 0 and s1[-1] == ' ': s1 = s1[:len(s1) - 1:] + s[i] else: s1 += s[i] s2 = '' else: s2 += s[i] s1 += s[i] if len(s2) > 1 and Dif(s2): s1 += ' ' s2 = '' s = s1 print(s) ``` No

Provide tags and a correct Python 3 solution for this coding contest problem. When registering in a social network, users are allowed to create their own convenient login to make it easier to share contacts, print it on business cards, etc. Login is an arbitrary sequence of lower and uppercase latin letters, digits and underline symbols («_»). However, in order to decrease the number of frauds and user-inattention related issues, it is prohibited to register a login if it is similar with an already existing login. More precisely, two logins s and t are considered similar if we can transform s to t via a sequence of operations of the following types: * transform lowercase letters to uppercase and vice versa; * change letter «O» (uppercase latin letter) to digit «0» and vice versa; * change digit «1» (one) to any letter among «l» (lowercase latin «L»), «I» (uppercase latin «i») and vice versa, or change one of these letters to other. For example, logins «Codeforces» and «codef0rces» as well as «OO0OOO00O0OOO0O00OOO0OO_lol» and «OO0OOO0O00OOO0O00OO0OOO_1oI» are considered similar whereas «Codeforces» and «Code_forces» are not. You're given a list of existing logins with no two similar amonst and a newly created user login. Check whether this new login is similar with any of the existing ones. Input The first line contains a non-empty string s consisting of lower and uppercase latin letters, digits and underline symbols («_») with length not exceeding 50 — the login itself. The second line contains a single integer n (1 ≤ n ≤ 1 000) — the number of existing logins. The next n lines describe the existing logins, following the same constraints as the user login (refer to the first line of the input). It's guaranteed that no two existing logins are similar. Output Print «Yes» (without quotes), if user can register via this login, i.e. none of the existing logins is similar with it. Otherwise print «No» (without quotes). Examples Input 1_wat 2 2_wat wat_1 Output Yes Input 000 3 00 ooA oOo Output No Input _i_ 3 __i_ _1_ I Output No Input La0 3 2a0 La1 1a0 Output No Input abc 1 aBc Output No Input 0Lil 2 LIL0 0Ril Output Yes Note In the second sample case the user wants to create a login consisting of three zeros. It's impossible due to collision with the third among the existing. In the third sample case the new login is similar with the second one. Tags: *special, strings Correct Solution: ``` s1 = input() abc = 'qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM' for y in range(0, 26): s1 = s1.replace(abc[y], abc[y + 26]) s1 = s1.replace("O", "0") s1 = s1.replace("L", "1") s1 = s1.replace("I", "1") n=int(input()) d=[] d.append(s1) for i in range(0,n): s=input() for y in range(0,26): s = s.replace(abc[y],abc[y+26]) s = s.replace("O", "0") s = s.replace("L","1") s = s.replace("I","1") if not s in d: d.append(s) if len(d) != n + 1: print('No') else: print('Yes') ```

Provide tags and a correct Python 3 solution for this coding contest problem. When registering in a social network, users are allowed to create their own convenient login to make it easier to share contacts, print it on business cards, etc. Login is an arbitrary sequence of lower and uppercase latin letters, digits and underline symbols («_»). However, in order to decrease the number of frauds and user-inattention related issues, it is prohibited to register a login if it is similar with an already existing login. More precisely, two logins s and t are considered similar if we can transform s to t via a sequence of operations of the following types: * transform lowercase letters to uppercase and vice versa; * change letter «O» (uppercase latin letter) to digit «0» and vice versa; * change digit «1» (one) to any letter among «l» (lowercase latin «L»), «I» (uppercase latin «i») and vice versa, or change one of these letters to other. For example, logins «Codeforces» and «codef0rces» as well as «OO0OOO00O0OOO0O00OOO0OO_lol» and «OO0OOO0O00OOO0O00OO0OOO_1oI» are considered similar whereas «Codeforces» and «Code_forces» are not. You're given a list of existing logins with no two similar amonst and a newly created user login. Check whether this new login is similar with any of the existing ones. Input The first line contains a non-empty string s consisting of lower and uppercase latin letters, digits and underline symbols («_») with length not exceeding 50 — the login itself. The second line contains a single integer n (1 ≤ n ≤ 1 000) — the number of existing logins. The next n lines describe the existing logins, following the same constraints as the user login (refer to the first line of the input). It's guaranteed that no two existing logins are similar. Output Print «Yes» (without quotes), if user can register via this login, i.e. none of the existing logins is similar with it. Otherwise print «No» (without quotes). Examples Input 1_wat 2 2_wat wat_1 Output Yes Input 000 3 00 ooA oOo Output No Input _i_ 3 __i_ _1_ I Output No Input La0 3 2a0 La1 1a0 Output No Input abc 1 aBc Output No Input 0Lil 2 LIL0 0Ril Output Yes Note In the second sample case the user wants to create a login consisting of three zeros. It's impossible due to collision with the third among the existing. In the third sample case the new login is similar with the second one. Tags: *special, strings Correct Solution: ``` def norm(s): d = ord('A') - ord('a') s11 = '' for i in range(len(s)): if ord('a') <= ord(s[i]) <= ord('z'): s11 += chr(ord(s[i]) + d) else: s11 += s[i] s = s11 s = s.replace('O', '0') s = s.replace('L', '1') s = s.replace('I', '1') return s s = norm(input()) n = int(input()) ok = True for i in range(n): s1 = input() if norm(s1) == s: ok = False break if ok: print('Yes') else: print('No') ```

Provide tags and a correct Python 3 solution for this coding contest problem. When registering in a social network, users are allowed to create their own convenient login to make it easier to share contacts, print it on business cards, etc. Login is an arbitrary sequence of lower and uppercase latin letters, digits and underline symbols («_»). However, in order to decrease the number of frauds and user-inattention related issues, it is prohibited to register a login if it is similar with an already existing login. More precisely, two logins s and t are considered similar if we can transform s to t via a sequence of operations of the following types: * transform lowercase letters to uppercase and vice versa; * change letter «O» (uppercase latin letter) to digit «0» and vice versa; * change digit «1» (one) to any letter among «l» (lowercase latin «L»), «I» (uppercase latin «i») and vice versa, or change one of these letters to other. For example, logins «Codeforces» and «codef0rces» as well as «OO0OOO00O0OOO0O00OOO0OO_lol» and «OO0OOO0O00OOO0O00OO0OOO_1oI» are considered similar whereas «Codeforces» and «Code_forces» are not. You're given a list of existing logins with no two similar amonst and a newly created user login. Check whether this new login is similar with any of the existing ones. Input The first line contains a non-empty string s consisting of lower and uppercase latin letters, digits and underline symbols («_») with length not exceeding 50 — the login itself. The second line contains a single integer n (1 ≤ n ≤ 1 000) — the number of existing logins. The next n lines describe the existing logins, following the same constraints as the user login (refer to the first line of the input). It's guaranteed that no two existing logins are similar. Output Print «Yes» (without quotes), if user can register via this login, i.e. none of the existing logins is similar with it. Otherwise print «No» (without quotes). Examples Input 1_wat 2 2_wat wat_1 Output Yes Input 000 3 00 ooA oOo Output No Input _i_ 3 __i_ _1_ I Output No Input La0 3 2a0 La1 1a0 Output No Input abc 1 aBc Output No Input 0Lil 2 LIL0 0Ril Output Yes Note In the second sample case the user wants to create a login consisting of three zeros. It's impossible due to collision with the third among the existing. In the third sample case the new login is similar with the second one. Tags: *special, strings Correct Solution: ``` s,n=input(),int(input()) s=s.replace('O','0') s=s.replace('o','0') for _ in range(n): stp='' a=input() if len(a)==len(s): for i in range(len(a)): if a[i] in '1lILi' and s[i] in '1lILi': stp+=a[i] else: stp+=s[i] a=a.replace('O','0') a=a.replace('o','0') stp=stp.lower() a=a.lower() if a==stp: print('No') break else: print('Yes') ```

Provide tags and a correct Python 3 solution for this coding contest problem. When registering in a social network, users are allowed to create their own convenient login to make it easier to share contacts, print it on business cards, etc. Login is an arbitrary sequence of lower and uppercase latin letters, digits and underline symbols («_»). However, in order to decrease the number of frauds and user-inattention related issues, it is prohibited to register a login if it is similar with an already existing login. More precisely, two logins s and t are considered similar if we can transform s to t via a sequence of operations of the following types: * transform lowercase letters to uppercase and vice versa; * change letter «O» (uppercase latin letter) to digit «0» and vice versa; * change digit «1» (one) to any letter among «l» (lowercase latin «L»), «I» (uppercase latin «i») and vice versa, or change one of these letters to other. For example, logins «Codeforces» and «codef0rces» as well as «OO0OOO00O0OOO0O00OOO0OO_lol» and «OO0OOO0O00OOO0O00OO0OOO_1oI» are considered similar whereas «Codeforces» and «Code_forces» are not. You're given a list of existing logins with no two similar amonst and a newly created user login. Check whether this new login is similar with any of the existing ones. Input The first line contains a non-empty string s consisting of lower and uppercase latin letters, digits and underline symbols («_») with length not exceeding 50 — the login itself. The second line contains a single integer n (1 ≤ n ≤ 1 000) — the number of existing logins. The next n lines describe the existing logins, following the same constraints as the user login (refer to the first line of the input). It's guaranteed that no two existing logins are similar. Output Print «Yes» (without quotes), if user can register via this login, i.e. none of the existing logins is similar with it. Otherwise print «No» (without quotes). Examples Input 1_wat 2 2_wat wat_1 Output Yes Input 000 3 00 ooA oOo Output No Input _i_ 3 __i_ _1_ I Output No Input La0 3 2a0 La1 1a0 Output No Input abc 1 aBc Output No Input 0Lil 2 LIL0 0Ril Output Yes Note In the second sample case the user wants to create a login consisting of three zeros. It's impossible due to collision with the third among the existing. In the third sample case the new login is similar with the second one. Tags: *special, strings Correct Solution: ``` def is_similar(one, two): one = one.lower() two = two.lower() one = one.replace('o', '0') one = one.replace('i', '1') one = one.replace('l', '1') two = two.replace('o', '0') two = two.replace('i', '1') two = two.replace('l', '1') return one == two have_similar = False newlogin = input() counter = int(input()) for i in range(0, counter): login = input() if is_similar(newlogin, login): have_similar = True break if have_similar: print("No") else: print("Yes") ```

Provide tags and a correct Python 3 solution for this coding contest problem. When registering in a social network, users are allowed to create their own convenient login to make it easier to share contacts, print it on business cards, etc. Login is an arbitrary sequence of lower and uppercase latin letters, digits and underline symbols («_»). However, in order to decrease the number of frauds and user-inattention related issues, it is prohibited to register a login if it is similar with an already existing login. More precisely, two logins s and t are considered similar if we can transform s to t via a sequence of operations of the following types: * transform lowercase letters to uppercase and vice versa; * change letter «O» (uppercase latin letter) to digit «0» and vice versa; * change digit «1» (one) to any letter among «l» (lowercase latin «L»), «I» (uppercase latin «i») and vice versa, or change one of these letters to other. For example, logins «Codeforces» and «codef0rces» as well as «OO0OOO00O0OOO0O00OOO0OO_lol» and «OO0OOO0O00OOO0O00OO0OOO_1oI» are considered similar whereas «Codeforces» and «Code_forces» are not. You're given a list of existing logins with no two similar amonst and a newly created user login. Check whether this new login is similar with any of the existing ones. Input The first line contains a non-empty string s consisting of lower and uppercase latin letters, digits and underline symbols («_») with length not exceeding 50 — the login itself. The second line contains a single integer n (1 ≤ n ≤ 1 000) — the number of existing logins. The next n lines describe the existing logins, following the same constraints as the user login (refer to the first line of the input). It's guaranteed that no two existing logins are similar. Output Print «Yes» (without quotes), if user can register via this login, i.e. none of the existing logins is similar with it. Otherwise print «No» (without quotes). Examples Input 1_wat 2 2_wat wat_1 Output Yes Input 000 3 00 ooA oOo Output No Input _i_ 3 __i_ _1_ I Output No Input La0 3 2a0 La1 1a0 Output No Input abc 1 aBc Output No Input 0Lil 2 LIL0 0Ril Output Yes Note In the second sample case the user wants to create a login consisting of three zeros. It's impossible due to collision with the third among the existing. In the third sample case the new login is similar with the second one. Tags: *special, strings Correct Solution: ``` def convert(s): s = s.lower() s = s.replace("0", "o") s = s.replace("1", "l") s = s.replace("i", "l") return s s = input() s = convert(s) n = int(input()) for i in range(n): s1 = convert(input()) if s == s1: print("No") exit(0) print("Yes") ```

Provide tags and a correct Python 3 solution for this coding contest problem. When registering in a social network, users are allowed to create their own convenient login to make it easier to share contacts, print it on business cards, etc. Login is an arbitrary sequence of lower and uppercase latin letters, digits and underline symbols («_»). However, in order to decrease the number of frauds and user-inattention related issues, it is prohibited to register a login if it is similar with an already existing login. More precisely, two logins s and t are considered similar if we can transform s to t via a sequence of operations of the following types: * transform lowercase letters to uppercase and vice versa; * change letter «O» (uppercase latin letter) to digit «0» and vice versa; * change digit «1» (one) to any letter among «l» (lowercase latin «L»), «I» (uppercase latin «i») and vice versa, or change one of these letters to other. For example, logins «Codeforces» and «codef0rces» as well as «OO0OOO00O0OOO0O00OOO0OO_lol» and «OO0OOO0O00OOO0O00OO0OOO_1oI» are considered similar whereas «Codeforces» and «Code_forces» are not. You're given a list of existing logins with no two similar amonst and a newly created user login. Check whether this new login is similar with any of the existing ones. Input The first line contains a non-empty string s consisting of lower and uppercase latin letters, digits and underline symbols («_») with length not exceeding 50 — the login itself. The second line contains a single integer n (1 ≤ n ≤ 1 000) — the number of existing logins. The next n lines describe the existing logins, following the same constraints as the user login (refer to the first line of the input). It's guaranteed that no two existing logins are similar. Output Print «Yes» (without quotes), if user can register via this login, i.e. none of the existing logins is similar with it. Otherwise print «No» (without quotes). Examples Input 1_wat 2 2_wat wat_1 Output Yes Input 000 3 00 ooA oOo Output No Input _i_ 3 __i_ _1_ I Output No Input La0 3 2a0 La1 1a0 Output No Input abc 1 aBc Output No Input 0Lil 2 LIL0 0Ril Output Yes Note In the second sample case the user wants to create a login consisting of three zeros. It's impossible due to collision with the third among the existing. In the third sample case the new login is similar with the second one. Tags: *special, strings Correct Solution: ``` def transf(s): return s.lower().replace('o', '0').replace('l', '1').replace('i', '1') def check(): s = input() n = int(input()) for i in range(n): l = input() if len(s) != len(l): continue if transf(s) == transf(l): return 'No' return 'Yes' print(check()) ```

Provide tags and a correct Python 3 solution for this coding contest problem. When registering in a social network, users are allowed to create their own convenient login to make it easier to share contacts, print it on business cards, etc. Login is an arbitrary sequence of lower and uppercase latin letters, digits and underline symbols («_»). However, in order to decrease the number of frauds and user-inattention related issues, it is prohibited to register a login if it is similar with an already existing login. More precisely, two logins s and t are considered similar if we can transform s to t via a sequence of operations of the following types: * transform lowercase letters to uppercase and vice versa; * change letter «O» (uppercase latin letter) to digit «0» and vice versa; * change digit «1» (one) to any letter among «l» (lowercase latin «L»), «I» (uppercase latin «i») and vice versa, or change one of these letters to other. For example, logins «Codeforces» and «codef0rces» as well as «OO0OOO00O0OOO0O00OOO0OO_lol» and «OO0OOO0O00OOO0O00OO0OOO_1oI» are considered similar whereas «Codeforces» and «Code_forces» are not. You're given a list of existing logins with no two similar amonst and a newly created user login. Check whether this new login is similar with any of the existing ones. Input The first line contains a non-empty string s consisting of lower and uppercase latin letters, digits and underline symbols («_») with length not exceeding 50 — the login itself. The second line contains a single integer n (1 ≤ n ≤ 1 000) — the number of existing logins. The next n lines describe the existing logins, following the same constraints as the user login (refer to the first line of the input). It's guaranteed that no two existing logins are similar. Output Print «Yes» (without quotes), if user can register via this login, i.e. none of the existing logins is similar with it. Otherwise print «No» (without quotes). Examples Input 1_wat 2 2_wat wat_1 Output Yes Input 000 3 00 ooA oOo Output No Input _i_ 3 __i_ _1_ I Output No Input La0 3 2a0 La1 1a0 Output No Input abc 1 aBc Output No Input 0Lil 2 LIL0 0Ril Output Yes Note In the second sample case the user wants to create a login consisting of three zeros. It's impossible due to collision with the third among the existing. In the third sample case the new login is similar with the second one. Tags: *special, strings Correct Solution: ``` def normalize_login(login): return login \ .lower() \ .replace("o", "0") \ .replace("i", "1") \ .replace("l", "1") new_login = normalize_login(input()) n = int(input()) logins = [] for i in range(0, n): login = normalize_login(input()) logins.append(login) print("No" if new_login in logins else "Yes") ```

Provide tags and a correct Python 3 solution for this coding contest problem. When registering in a social network, users are allowed to create their own convenient login to make it easier to share contacts, print it on business cards, etc. Login is an arbitrary sequence of lower and uppercase latin letters, digits and underline symbols («_»). However, in order to decrease the number of frauds and user-inattention related issues, it is prohibited to register a login if it is similar with an already existing login. More precisely, two logins s and t are considered similar if we can transform s to t via a sequence of operations of the following types: * transform lowercase letters to uppercase and vice versa; * change letter «O» (uppercase latin letter) to digit «0» and vice versa; * change digit «1» (one) to any letter among «l» (lowercase latin «L»), «I» (uppercase latin «i») and vice versa, or change one of these letters to other. For example, logins «Codeforces» and «codef0rces» as well as «OO0OOO00O0OOO0O00OOO0OO_lol» and «OO0OOO0O00OOO0O00OO0OOO_1oI» are considered similar whereas «Codeforces» and «Code_forces» are not. You're given a list of existing logins with no two similar amonst and a newly created user login. Check whether this new login is similar with any of the existing ones. Input The first line contains a non-empty string s consisting of lower and uppercase latin letters, digits and underline symbols («_») with length not exceeding 50 — the login itself. The second line contains a single integer n (1 ≤ n ≤ 1 000) — the number of existing logins. The next n lines describe the existing logins, following the same constraints as the user login (refer to the first line of the input). It's guaranteed that no two existing logins are similar. Output Print «Yes» (without quotes), if user can register via this login, i.e. none of the existing logins is similar with it. Otherwise print «No» (without quotes). Examples Input 1_wat 2 2_wat wat_1 Output Yes Input 000 3 00 ooA oOo Output No Input _i_ 3 __i_ _1_ I Output No Input La0 3 2a0 La1 1a0 Output No Input abc 1 aBc Output No Input 0Lil 2 LIL0 0Ril Output Yes Note In the second sample case the user wants to create a login consisting of three zeros. It's impossible due to collision with the third among the existing. In the third sample case the new login is similar with the second one. Tags: *special, strings Correct Solution: ``` def rep(data): data = data.replace("0", "@@@") data = data.replace("o", "@@@") data = data.replace("1", "!!!") data = data.replace("l", "!!!") data = data.replace("i", "!!!") return data login_usr = rep(input().lower()) count_log = int(input()) data_log = list(map(rep, [input().lower() for i in range(count_log)])) for data in data_log: if data == login_usr: count_log = 0 break else: count_log = 1 if count_log: print("Yes") else: print("No") ```

Provide tags and a correct Python 3 solution for this coding contest problem. Recently, a start up by two students of a state university of city F gained incredible popularity. Now it's time to start a new company. But what do we call it? The market analysts came up with a very smart plan: the name of the company should be identical to its reflection in a mirror! In other words, if we write out the name of the company on a piece of paper in a line (horizontally, from left to right) with large English letters, then put this piece of paper in front of the mirror, then the reflection of the name in the mirror should perfectly match the line written on the piece of paper. There are many suggestions for the company name, so coming up to the mirror with a piece of paper for each name wouldn't be sensible. The founders of the company decided to automatize this process. They asked you to write a program that can, given a word, determine whether the word is a 'mirror' word or not. Input The first line contains a non-empty name that needs to be checked. The name contains at most 105 large English letters. The name will be written with the next sans serif font: <image> Output Print 'YES' (without the quotes), if the given name matches its mirror reflection. Otherwise, print 'NO' (without the quotes). Examples Input AHA Output YES Input Z Output NO Input XO Output NO Tags: implementation Correct Solution: ``` symmetric = 'AHIMOTUVWXY' s = input() if s == s[::-1] and all([x in symmetric for x in s]): print('YES') else: print('NO') ```

Provide tags and a correct Python 3 solution for this coding contest problem. Recently, a start up by two students of a state university of city F gained incredible popularity. Now it's time to start a new company. But what do we call it? The market analysts came up with a very smart plan: the name of the company should be identical to its reflection in a mirror! In other words, if we write out the name of the company on a piece of paper in a line (horizontally, from left to right) with large English letters, then put this piece of paper in front of the mirror, then the reflection of the name in the mirror should perfectly match the line written on the piece of paper. There are many suggestions for the company name, so coming up to the mirror with a piece of paper for each name wouldn't be sensible. The founders of the company decided to automatize this process. They asked you to write a program that can, given a word, determine whether the word is a 'mirror' word or not. Input The first line contains a non-empty name that needs to be checked. The name contains at most 105 large English letters. The name will be written with the next sans serif font: <image> Output Print 'YES' (without the quotes), if the given name matches its mirror reflection. Otherwise, print 'NO' (without the quotes). Examples Input AHA Output YES Input Z Output NO Input XO Output NO Tags: implementation Correct Solution: ``` '''input XO ''' s = input() if all(s[x] == s[~x] for x in range(len(s)//2)): if any(y not in "AHIMOTUVWXY" for y in s[:len(s)//2+1]): print("NO") else: print("YES") else: print("NO") ```

Provide tags and a correct Python 3 solution for this coding contest problem. Recently, a start up by two students of a state university of city F gained incredible popularity. Now it's time to start a new company. But what do we call it? The market analysts came up with a very smart plan: the name of the company should be identical to its reflection in a mirror! In other words, if we write out the name of the company on a piece of paper in a line (horizontally, from left to right) with large English letters, then put this piece of paper in front of the mirror, then the reflection of the name in the mirror should perfectly match the line written on the piece of paper. There are many suggestions for the company name, so coming up to the mirror with a piece of paper for each name wouldn't be sensible. The founders of the company decided to automatize this process. They asked you to write a program that can, given a word, determine whether the word is a 'mirror' word or not. Input The first line contains a non-empty name that needs to be checked. The name contains at most 105 large English letters. The name will be written with the next sans serif font: <image> Output Print 'YES' (without the quotes), if the given name matches its mirror reflection. Otherwise, print 'NO' (without the quotes). Examples Input AHA Output YES Input Z Output NO Input XO Output NO Tags: implementation Correct Solution: ``` def palindrome(n): for i in range(0,len(n)): if n[i] != n[-(i+1)]: return 0 return 1 lessgo = ['a','h','i','m','o','t','u','v','w','x','y'] i = list(input()) for j in range(len(i)): i[j] = i[j].lower() mir = 1 for j in range(len(i)): if i[j] not in lessgo: mir = 0 if palindrome(i) == 1 and mir == 1: print("YES") else: print("NO") ```

Provide tags and a correct Python 3 solution for this coding contest problem. Recently, a start up by two students of a state university of city F gained incredible popularity. Now it's time to start a new company. But what do we call it? The market analysts came up with a very smart plan: the name of the company should be identical to its reflection in a mirror! In other words, if we write out the name of the company on a piece of paper in a line (horizontally, from left to right) with large English letters, then put this piece of paper in front of the mirror, then the reflection of the name in the mirror should perfectly match the line written on the piece of paper. There are many suggestions for the company name, so coming up to the mirror with a piece of paper for each name wouldn't be sensible. The founders of the company decided to automatize this process. They asked you to write a program that can, given a word, determine whether the word is a 'mirror' word or not. Input The first line contains a non-empty name that needs to be checked. The name contains at most 105 large English letters. The name will be written with the next sans serif font: <image> Output Print 'YES' (without the quotes), if the given name matches its mirror reflection. Otherwise, print 'NO' (without the quotes). Examples Input AHA Output YES Input Z Output NO Input XO Output NO Tags: implementation Correct Solution: ``` s = input() print('YES' if all(ch in 'AHIMOTUVWXY' for ch in s) and s==s[::-1] else 'NO') ```

Provide tags and a correct Python 3 solution for this coding contest problem. Recently, a start up by two students of a state university of city F gained incredible popularity. Now it's time to start a new company. But what do we call it? The market analysts came up with a very smart plan: the name of the company should be identical to its reflection in a mirror! In other words, if we write out the name of the company on a piece of paper in a line (horizontally, from left to right) with large English letters, then put this piece of paper in front of the mirror, then the reflection of the name in the mirror should perfectly match the line written on the piece of paper. There are many suggestions for the company name, so coming up to the mirror with a piece of paper for each name wouldn't be sensible. The founders of the company decided to automatize this process. They asked you to write a program that can, given a word, determine whether the word is a 'mirror' word or not. Input The first line contains a non-empty name that needs to be checked. The name contains at most 105 large English letters. The name will be written with the next sans serif font: <image> Output Print 'YES' (without the quotes), if the given name matches its mirror reflection. Otherwise, print 'NO' (without the quotes). Examples Input AHA Output YES Input Z Output NO Input XO Output NO Tags: implementation Correct Solution: ``` n=input() i=0 k=len(n)-1 _b=True while i<=k and _b: if n[i]==n[k] and n[i] in ['A','H','I','M','O','T','U','V','W','X','Y']: _b=True i+=1 k-=1 else: _b=False if _b: print('YES') else: print('NO') ```

Provide tags and a correct Python 3 solution for this coding contest problem. Recently, a start up by two students of a state university of city F gained incredible popularity. Now it's time to start a new company. But what do we call it? The market analysts came up with a very smart plan: the name of the company should be identical to its reflection in a mirror! In other words, if we write out the name of the company on a piece of paper in a line (horizontally, from left to right) with large English letters, then put this piece of paper in front of the mirror, then the reflection of the name in the mirror should perfectly match the line written on the piece of paper. There are many suggestions for the company name, so coming up to the mirror with a piece of paper for each name wouldn't be sensible. The founders of the company decided to automatize this process. They asked you to write a program that can, given a word, determine whether the word is a 'mirror' word or not. Input The first line contains a non-empty name that needs to be checked. The name contains at most 105 large English letters. The name will be written with the next sans serif font: <image> Output Print 'YES' (without the quotes), if the given name matches its mirror reflection. Otherwise, print 'NO' (without the quotes). Examples Input AHA Output YES Input Z Output NO Input XO Output NO Tags: implementation Correct Solution: ``` n=list(input()) m=n+[] m.reverse() l=['A','H','I','M','O','T','U','V','W','X','Y'] if(m==n ): e=0 for i in range(len(n)): if n[i] not in l: print("NO") e=1 break if(e==0): print("YES") else: print("NO") ```

Provide tags and a correct Python 3 solution for this coding contest problem. Recently, a start up by two students of a state university of city F gained incredible popularity. Now it's time to start a new company. But what do we call it? The market analysts came up with a very smart plan: the name of the company should be identical to its reflection in a mirror! In other words, if we write out the name of the company on a piece of paper in a line (horizontally, from left to right) with large English letters, then put this piece of paper in front of the mirror, then the reflection of the name in the mirror should perfectly match the line written on the piece of paper. There are many suggestions for the company name, so coming up to the mirror with a piece of paper for each name wouldn't be sensible. The founders of the company decided to automatize this process. They asked you to write a program that can, given a word, determine whether the word is a 'mirror' word or not. Input The first line contains a non-empty name that needs to be checked. The name contains at most 105 large English letters. The name will be written with the next sans serif font: <image> Output Print 'YES' (without the quotes), if the given name matches its mirror reflection. Otherwise, print 'NO' (without the quotes). Examples Input AHA Output YES Input Z Output NO Input XO Output NO Tags: implementation Correct Solution: ``` s = input() a = ['A','H','I','M','O','T','U','V','W','X','Y'] a = set(a) count = 0 if len(s)%2 == 0: for i in range(int(len(s)/2)): if s[i] == s[len(s)-i-1] and s[i] in a: count = count + 1 else : if s[int(len(s)/2)] in a: for i in range(int(len(s)/2)): if s[i] == s[len(s)-i-1] and s[i] in a: count = count + 1 if count == int(len(s)/2) and s[0] in a : print("YES") else: print("NO") ```

Provide tags and a correct Python 3 solution for this coding contest problem. Recently, a start up by two students of a state university of city F gained incredible popularity. Now it's time to start a new company. But what do we call it? The market analysts came up with a very smart plan: the name of the company should be identical to its reflection in a mirror! In other words, if we write out the name of the company on a piece of paper in a line (horizontally, from left to right) with large English letters, then put this piece of paper in front of the mirror, then the reflection of the name in the mirror should perfectly match the line written on the piece of paper. There are many suggestions for the company name, so coming up to the mirror with a piece of paper for each name wouldn't be sensible. The founders of the company decided to automatize this process. They asked you to write a program that can, given a word, determine whether the word is a 'mirror' word or not. Input The first line contains a non-empty name that needs to be checked. The name contains at most 105 large English letters. The name will be written with the next sans serif font: <image> Output Print 'YES' (without the quotes), if the given name matches its mirror reflection. Otherwise, print 'NO' (without the quotes). Examples Input AHA Output YES Input Z Output NO Input XO Output NO Tags: implementation Correct Solution: ``` def ic(s): ss=set('AHIMOTUVWXY') m=len(s)//2+1 for c in range(m): if s[c]!=s[-(c+1)] or s[c] not in ss: return 0 return 1 s='YES' if ic(input()) else 'NO' print(s) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Each employee of the "Blake Techologies" company uses a special messaging app "Blake Messenger". All the stuff likes this app and uses it constantly. However, some important futures are missing. For example, many users want to be able to search through the message history. It was already announced that the new feature will appear in the nearest update, when developers faced some troubles that only you may help them to solve. All the messages are represented as a strings consisting of only lowercase English letters. In order to reduce the network load strings are represented in the special compressed form. Compression algorithm works as follows: string is represented as a concatenation of n blocks, each block containing only equal characters. One block may be described as a pair (li, ci), where li is the length of the i-th block and ci is the corresponding letter. Thus, the string s may be written as the sequence of pairs <image>. Your task is to write the program, that given two compressed string t and s finds all occurrences of s in t. Developers know that there may be many such occurrences, so they only ask you to find the number of them. Note that p is the starting position of some occurrence of s in t if and only if tptp + 1...tp + |s| - 1 = s, where ti is the i-th character of string t. Note that the way to represent the string in compressed form may not be unique. For example string "aaaa" may be given as <image>, <image>, <image>... Input The first line of the input contains two integers n and m (1 ≤ n, m ≤ 200 000) — the number of blocks in the strings t and s, respectively. The second line contains the descriptions of n parts of string t in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. The second line contains the descriptions of m parts of string s in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. Output Print a single integer — the number of occurrences of s in t. Examples Input 5 3 3-a 2-b 4-c 3-a 2-c 2-a 2-b 1-c Output 1 Input 6 1 3-a 6-b 7-a 4-c 8-e 2-a 3-a Output 6 Input 5 5 1-h 1-e 1-l 1-l 1-o 1-w 1-o 1-r 1-l 1-d Output 0 Note In the first sample, t = "aaabbccccaaacc", and string s = "aabbc". The only occurrence of string s in string t starts at position p = 2. In the second sample, t = "aaabbbbbbaaaaaaacccceeeeeeeeaa", and s = "aaa". The occurrences of s in t start at positions p = 1, p = 10, p = 11, p = 12, p = 13 and p = 14.

Provide tags and a correct Python 3 solution for this coding contest problem. Each employee of the "Blake Techologies" company uses a special messaging app "Blake Messenger". All the stuff likes this app and uses it constantly. However, some important futures are missing. For example, many users want to be able to search through the message history. It was already announced that the new feature will appear in the nearest update, when developers faced some troubles that only you may help them to solve. All the messages are represented as a strings consisting of only lowercase English letters. In order to reduce the network load strings are represented in the special compressed form. Compression algorithm works as follows: string is represented as a concatenation of n blocks, each block containing only equal characters. One block may be described as a pair (li, ci), where li is the length of the i-th block and ci is the corresponding letter. Thus, the string s may be written as the sequence of pairs <image>. Your task is to write the program, that given two compressed string t and s finds all occurrences of s in t. Developers know that there may be many such occurrences, so they only ask you to find the number of them. Note that p is the starting position of some occurrence of s in t if and only if tptp + 1...tp + |s| - 1 = s, where ti is the i-th character of string t. Note that the way to represent the string in compressed form may not be unique. For example string "aaaa" may be given as <image>, <image>, <image>... Input The first line of the input contains two integers n and m (1 ≤ n, m ≤ 200 000) — the number of blocks in the strings t and s, respectively. The second line contains the descriptions of n parts of string t in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. The second line contains the descriptions of m parts of string s in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. Output Print a single integer — the number of occurrences of s in t. Examples Input 5 3 3-a 2-b 4-c 3-a 2-c 2-a 2-b 1-c Output 1 Input 6 1 3-a 6-b 7-a 4-c 8-e 2-a 3-a Output 6 Input 5 5 1-h 1-e 1-l 1-l 1-o 1-w 1-o 1-r 1-l 1-d Output 0 Note In the first sample, t = "aaabbccccaaacc", and string s = "aabbc". The only occurrence of string s in string t starts at position p = 2. In the second sample, t = "aaabbbbbbaaaaaaacccceeeeeeeeaa", and s = "aaa". The occurrences of s in t start at positions p = 1, p = 10, p = 11, p = 12, p = 13 and p = 14. Tags: data structures, hashing, implementation, string suffix structures, strings Correct Solution: ``` def ziped(a): p = [] for i in a: x = int(i.split('-')[0]) y = i.split('-')[1] if len(p) > 0 and p[-1][1] == y: p[-1][0] += x else: p.append([x, y]) return p def solve(a, b , c): ans = 0 if len(b) == 1: for token in a: if c(token, b[0]): ans += token[0] - b[0][0] + 1 return ans if len(b) == 2: for i in range(len(a) - 1): if c(a[i], b[0]) and c(a[i + 1], b[-1]): ans += 1 return ans v = b[1 : -1] + [[100500, '#']] + a p = [0] * len(v) for i in range(1, len(v)): j = p[i - 1] while j > 0 and v[i] != v[j]: j = p[j - 1] if v[i] == v[j]: j += 1 p[i] = j for i in range(len(v) - 1): if p[i] == len(b) - 2 and c(v[i - p[i]], b[0]) and c(v[i + 1], b[-1]): ans += 1 return ans n, m = map(int, input().split()) a = ziped(input().split()) b = ziped(input().split()) print(solve(a, b, lambda x, y: x[1] == y[1] and x[0] >= y[0])) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Each employee of the "Blake Techologies" company uses a special messaging app "Blake Messenger". All the stuff likes this app and uses it constantly. However, some important futures are missing. For example, many users want to be able to search through the message history. It was already announced that the new feature will appear in the nearest update, when developers faced some troubles that only you may help them to solve. All the messages are represented as a strings consisting of only lowercase English letters. In order to reduce the network load strings are represented in the special compressed form. Compression algorithm works as follows: string is represented as a concatenation of n blocks, each block containing only equal characters. One block may be described as a pair (li, ci), where li is the length of the i-th block and ci is the corresponding letter. Thus, the string s may be written as the sequence of pairs <image>. Your task is to write the program, that given two compressed string t and s finds all occurrences of s in t. Developers know that there may be many such occurrences, so they only ask you to find the number of them. Note that p is the starting position of some occurrence of s in t if and only if tptp + 1...tp + |s| - 1 = s, where ti is the i-th character of string t. Note that the way to represent the string in compressed form may not be unique. For example string "aaaa" may be given as <image>, <image>, <image>... Input The first line of the input contains two integers n and m (1 ≤ n, m ≤ 200 000) — the number of blocks in the strings t and s, respectively. The second line contains the descriptions of n parts of string t in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. The second line contains the descriptions of m parts of string s in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. Output Print a single integer — the number of occurrences of s in t. Examples Input 5 3 3-a 2-b 4-c 3-a 2-c 2-a 2-b 1-c Output 1 Input 6 1 3-a 6-b 7-a 4-c 8-e 2-a 3-a Output 6 Input 5 5 1-h 1-e 1-l 1-l 1-o 1-w 1-o 1-r 1-l 1-d Output 0 Note In the first sample, t = "aaabbccccaaacc", and string s = "aabbc". The only occurrence of string s in string t starts at position p = 2. In the second sample, t = "aaabbbbbbaaaaaaacccceeeeeeeeaa", and s = "aaa". The occurrences of s in t start at positions p = 1, p = 10, p = 11, p = 12, p = 13 and p = 14.

Provide tags and a correct Python 3 solution for this coding contest problem. Each employee of the "Blake Techologies" company uses a special messaging app "Blake Messenger". All the stuff likes this app and uses it constantly. However, some important futures are missing. For example, many users want to be able to search through the message history. It was already announced that the new feature will appear in the nearest update, when developers faced some troubles that only you may help them to solve. All the messages are represented as a strings consisting of only lowercase English letters. In order to reduce the network load strings are represented in the special compressed form. Compression algorithm works as follows: string is represented as a concatenation of n blocks, each block containing only equal characters. One block may be described as a pair (li, ci), where li is the length of the i-th block and ci is the corresponding letter. Thus, the string s may be written as the sequence of pairs <image>. Your task is to write the program, that given two compressed string t and s finds all occurrences of s in t. Developers know that there may be many such occurrences, so they only ask you to find the number of them. Note that p is the starting position of some occurrence of s in t if and only if tptp + 1...tp + |s| - 1 = s, where ti is the i-th character of string t. Note that the way to represent the string in compressed form may not be unique. For example string "aaaa" may be given as <image>, <image>, <image>... Input The first line of the input contains two integers n and m (1 ≤ n, m ≤ 200 000) — the number of blocks in the strings t and s, respectively. The second line contains the descriptions of n parts of string t in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. The second line contains the descriptions of m parts of string s in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. Output Print a single integer — the number of occurrences of s in t. Examples Input 5 3 3-a 2-b 4-c 3-a 2-c 2-a 2-b 1-c Output 1 Input 6 1 3-a 6-b 7-a 4-c 8-e 2-a 3-a Output 6 Input 5 5 1-h 1-e 1-l 1-l 1-o 1-w 1-o 1-r 1-l 1-d Output 0 Note In the first sample, t = "aaabbccccaaacc", and string s = "aabbc". The only occurrence of string s in string t starts at position p = 2. In the second sample, t = "aaabbbbbbaaaaaaacccceeeeeeeeaa", and s = "aaa". The occurrences of s in t start at positions p = 1, p = 10, p = 11, p = 12, p = 13 and p = 14. Tags: data structures, hashing, implementation, string suffix structures, strings Correct Solution: ``` def ziped(a): p = [] for i in a: x = int(i.split('-')[0]) y = i.split('-')[1] if len(p) > 0 and p[-1][1] == y: p[-1][0] += x else: p.append([x, y]) return p def solve(a, b , c): ans = 0 if len(b) == 1: for token in a: #print("token",token) if c(token, b[0]): ans += token[0] - b[0][0] + 1 return ans if len(b) == 2: for i in range(len(a) - 1): if c(a[i], b[0]) and c(a[i + 1], b[-1]): ans += 1 return ans v = b[1 : -1] + [[100500, '#']] + a p = [0] * len(v) for i in range(1, len(v)): j = p[i - 1] while j > 0 and v[i] != v[j]: j = p[j - 1] if v[i] == v[j]: j += 1 p[i] = j for i in range(len(v) - 1): if p[i] == len(b) - 2 and c(v[i - p[i]], b[0]) and c(v[i + 1], b[-1]): ans += 1 return ans n, m = map(int, input().split()) a = ziped(input().split()) b = ziped(input().split()) print(solve(a, b, lambda x, y: x[1] == y[1] and x[0] >= y[0])) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Each employee of the "Blake Techologies" company uses a special messaging app "Blake Messenger". All the stuff likes this app and uses it constantly. However, some important futures are missing. For example, many users want to be able to search through the message history. It was already announced that the new feature will appear in the nearest update, when developers faced some troubles that only you may help them to solve. All the messages are represented as a strings consisting of only lowercase English letters. In order to reduce the network load strings are represented in the special compressed form. Compression algorithm works as follows: string is represented as a concatenation of n blocks, each block containing only equal characters. One block may be described as a pair (li, ci), where li is the length of the i-th block and ci is the corresponding letter. Thus, the string s may be written as the sequence of pairs <image>. Your task is to write the program, that given two compressed string t and s finds all occurrences of s in t. Developers know that there may be many such occurrences, so they only ask you to find the number of them. Note that p is the starting position of some occurrence of s in t if and only if tptp + 1...tp + |s| - 1 = s, where ti is the i-th character of string t. Note that the way to represent the string in compressed form may not be unique. For example string "aaaa" may be given as <image>, <image>, <image>... Input The first line of the input contains two integers n and m (1 ≤ n, m ≤ 200 000) — the number of blocks in the strings t and s, respectively. The second line contains the descriptions of n parts of string t in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. The second line contains the descriptions of m parts of string s in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. Output Print a single integer — the number of occurrences of s in t. Examples Input 5 3 3-a 2-b 4-c 3-a 2-c 2-a 2-b 1-c Output 1 Input 6 1 3-a 6-b 7-a 4-c 8-e 2-a 3-a Output 6 Input 5 5 1-h 1-e 1-l 1-l 1-o 1-w 1-o 1-r 1-l 1-d Output 0 Note In the first sample, t = "aaabbccccaaacc", and string s = "aabbc". The only occurrence of string s in string t starts at position p = 2. In the second sample, t = "aaabbbbbbaaaaaaacccceeeeeeeeaa", and s = "aaa". The occurrences of s in t start at positions p = 1, p = 10, p = 11, p = 12, p = 13 and p = 14.

Provide tags and a correct Python 3 solution for this coding contest problem. Each employee of the "Blake Techologies" company uses a special messaging app "Blake Messenger". All the stuff likes this app and uses it constantly. However, some important futures are missing. For example, many users want to be able to search through the message history. It was already announced that the new feature will appear in the nearest update, when developers faced some troubles that only you may help them to solve. All the messages are represented as a strings consisting of only lowercase English letters. In order to reduce the network load strings are represented in the special compressed form. Compression algorithm works as follows: string is represented as a concatenation of n blocks, each block containing only equal characters. One block may be described as a pair (li, ci), where li is the length of the i-th block and ci is the corresponding letter. Thus, the string s may be written as the sequence of pairs <image>. Your task is to write the program, that given two compressed string t and s finds all occurrences of s in t. Developers know that there may be many such occurrences, so they only ask you to find the number of them. Note that p is the starting position of some occurrence of s in t if and only if tptp + 1...tp + |s| - 1 = s, where ti is the i-th character of string t. Note that the way to represent the string in compressed form may not be unique. For example string "aaaa" may be given as <image>, <image>, <image>... Input The first line of the input contains two integers n and m (1 ≤ n, m ≤ 200 000) — the number of blocks in the strings t and s, respectively. The second line contains the descriptions of n parts of string t in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. The second line contains the descriptions of m parts of string s in the format "li-ci" (1 ≤ li ≤ 1 000 000) — the length of the i-th part and the corresponding lowercase English letter. Output Print a single integer — the number of occurrences of s in t. Examples Input 5 3 3-a 2-b 4-c 3-a 2-c 2-a 2-b 1-c Output 1 Input 6 1 3-a 6-b 7-a 4-c 8-e 2-a 3-a Output 6 Input 5 5 1-h 1-e 1-l 1-l 1-o 1-w 1-o 1-r 1-l 1-d Output 0 Note In the first sample, t = "aaabbccccaaacc", and string s = "aabbc". The only occurrence of string s in string t starts at position p = 2. In the second sample, t = "aaabbbbbbaaaaaaacccceeeeeeeeaa", and s = "aaa". The occurrences of s in t start at positions p = 1, p = 10, p = 11, p = 12, p = 13 and p = 14.

Provide tags and a correct Python 3 solution for this coding contest problem. This problem is different from the hard version. In this version Ujan makes exactly one exchange. You can hack this problem only if you solve both problems. After struggling and failing many times, Ujan decided to try to clean up his house again. He decided to get his strings in order first. Ujan has two distinct strings s and t of length n consisting of only of lowercase English characters. He wants to make them equal. Since Ujan is lazy, he will perform the following operation exactly once: he takes two positions i and j (1 ≤ i,j ≤ n, the values i and j can be equal or different), and swaps the characters s_i and t_j. Can he succeed? Note that he has to perform this operation exactly once. He has to perform this operation. Input The first line contains a single integer k (1 ≤ k ≤ 10), the number of test cases. For each of the test cases, the first line contains a single integer n (2 ≤ n ≤ 10^4), the length of the strings s and t. Each of the next two lines contains the strings s and t, each having length exactly n. The strings consist only of lowercase English letters. It is guaranteed that strings are different. Output For each test case, output "Yes" if Ujan can make the two strings equal and "No" otherwise. You can print each letter in any case (upper or lower). Example Input 4 5 souse houhe 3 cat dog 2 aa az 3 abc bca Output Yes No No No Note In the first test case, Ujan can swap characters s_1 and t_4, obtaining the word "house". In the second test case, it is not possible to make the strings equal using exactly one swap of s_i and t_j. Tags: strings Correct Solution: ``` k = int(input()) for _ in range(k): n = int(input()) s0 = input() t0 = input() s = [s0[i] for i in range(n)] t = [t0[i] for i in range(n)] ans = "Yes" ansArr = [] for i in range(n): if s[i] == t[i]: continue elif s[i] in s[i+1:]: ind = s.index(s[i], i+1, n) ansArr += [[ind+1, i+1]] s[ind], t[i] = t[i], s[ind] elif s[i] in t[i+1:]: ind = t.index(s[i], i+1, n) ansArr += [[i+1+1, ind+1]] s[i+1], t[ind] = t[ind], s[i+1] ansArr += [[i+1+1, i+1]] s[i+1], t[i] = t[i], s[i+1] else: ans = "No" break print(ans) if ans == "Yes": print(len(ansArr)) for item in ansArr: print(item[0], item[1]) ```

Provide tags and a correct Python 3 solution for this coding contest problem. This problem is different from the hard version. In this version Ujan makes exactly one exchange. You can hack this problem only if you solve both problems. After struggling and failing many times, Ujan decided to try to clean up his house again. He decided to get his strings in order first. Ujan has two distinct strings s and t of length n consisting of only of lowercase English characters. He wants to make them equal. Since Ujan is lazy, he will perform the following operation exactly once: he takes two positions i and j (1 ≤ i,j ≤ n, the values i and j can be equal or different), and swaps the characters s_i and t_j. Can he succeed? Note that he has to perform this operation exactly once. He has to perform this operation. Input The first line contains a single integer k (1 ≤ k ≤ 10), the number of test cases. For each of the test cases, the first line contains a single integer n (2 ≤ n ≤ 10^4), the length of the strings s and t. Each of the next two lines contains the strings s and t, each having length exactly n. The strings consist only of lowercase English letters. It is guaranteed that strings are different. Output For each test case, output "Yes" if Ujan can make the two strings equal and "No" otherwise. You can print each letter in any case (upper or lower). Example Input 4 5 souse houhe 3 cat dog 2 aa az 3 abc bca Output Yes No No No Note In the first test case, Ujan can swap characters s_1 and t_4, obtaining the word "house". In the second test case, it is not possible to make the strings equal using exactly one swap of s_i and t_j. Tags: strings Correct Solution: ``` Q = int(input()) Query = [] for _ in range(Q): N = int(input()) S1 = list(input()) S2 = list(input()) Query.append((N, S1, S2)) for N, S1, S2 in Query: C = [] for i in range(N): s1, s2 = S1[i], S2[i] if s1 != s2: C.append((s1, s2)) if len(C) == 0: print('Yes') elif len(C) == 2: if C[0][0] == C[1][0] and C[0][1] == C[1][1]: print('Yes') else: print("No") else: print("No") ```

Provide tags and a correct Python 3 solution for this coding contest problem. This problem is different from the hard version. In this version Ujan makes exactly one exchange. You can hack this problem only if you solve both problems. After struggling and failing many times, Ujan decided to try to clean up his house again. He decided to get his strings in order first. Ujan has two distinct strings s and t of length n consisting of only of lowercase English characters. He wants to make them equal. Since Ujan is lazy, he will perform the following operation exactly once: he takes two positions i and j (1 ≤ i,j ≤ n, the values i and j can be equal or different), and swaps the characters s_i and t_j. Can he succeed? Note that he has to perform this operation exactly once. He has to perform this operation. Input The first line contains a single integer k (1 ≤ k ≤ 10), the number of test cases. For each of the test cases, the first line contains a single integer n (2 ≤ n ≤ 10^4), the length of the strings s and t. Each of the next two lines contains the strings s and t, each having length exactly n. The strings consist only of lowercase English letters. It is guaranteed that strings are different. Output For each test case, output "Yes" if Ujan can make the two strings equal and "No" otherwise. You can print each letter in any case (upper or lower). Example Input 4 5 souse houhe 3 cat dog 2 aa az 3 abc bca Output Yes No No No Note In the first test case, Ujan can swap characters s_1 and t_4, obtaining the word "house". In the second test case, it is not possible to make the strings equal using exactly one swap of s_i and t_j.

Provide tags and a correct Python 3 solution for this coding contest problem. This problem is different from the hard version. In this version Ujan makes exactly one exchange. You can hack this problem only if you solve both problems. After struggling and failing many times, Ujan decided to try to clean up his house again. He decided to get his strings in order first. Ujan has two distinct strings s and t of length n consisting of only of lowercase English characters. He wants to make them equal. Since Ujan is lazy, he will perform the following operation exactly once: he takes two positions i and j (1 ≤ i,j ≤ n, the values i and j can be equal or different), and swaps the characters s_i and t_j. Can he succeed? Note that he has to perform this operation exactly once. He has to perform this operation. Input The first line contains a single integer k (1 ≤ k ≤ 10), the number of test cases. For each of the test cases, the first line contains a single integer n (2 ≤ n ≤ 10^4), the length of the strings s and t. Each of the next two lines contains the strings s and t, each having length exactly n. The strings consist only of lowercase English letters. It is guaranteed that strings are different. Output For each test case, output "Yes" if Ujan can make the two strings equal and "No" otherwise. You can print each letter in any case (upper or lower). Example Input 4 5 souse houhe 3 cat dog 2 aa az 3 abc bca Output Yes No No No Note In the first test case, Ujan can swap characters s_1 and t_4, obtaining the word "house". In the second test case, it is not possible to make the strings equal using exactly one swap of s_i and t_j. Tags: strings Correct Solution: ``` import sys input = lambda: sys.stdin.readline().strip() k = int(input()) for i in range(k): n = int(input()) s = list(input()) t = list(input()) res = [] for i in range(n): try: found = s.index(s[i], i+1) s[found], t[i] = t[i], s[found] res.append((found, i)) except: try: found = t.index(s[i], i) t[found], s[found] = s[found], t[found] res.append((found, found)) s[found], t[i] = t[i], s[found] res.append((found, i)) except: print('No') break else: print('Yes') print(len(res)) for i in res: print(i[0]+1, i[1]+1) ```

Provide tags and a correct Python 3 solution for this coding contest problem. This problem is different from the hard version. In this version Ujan makes exactly one exchange. You can hack this problem only if you solve both problems. After struggling and failing many times, Ujan decided to try to clean up his house again. He decided to get his strings in order first. Ujan has two distinct strings s and t of length n consisting of only of lowercase English characters. He wants to make them equal. Since Ujan is lazy, he will perform the following operation exactly once: he takes two positions i and j (1 ≤ i,j ≤ n, the values i and j can be equal or different), and swaps the characters s_i and t_j. Can he succeed? Note that he has to perform this operation exactly once. He has to perform this operation. Input The first line contains a single integer k (1 ≤ k ≤ 10), the number of test cases. For each of the test cases, the first line contains a single integer n (2 ≤ n ≤ 10^4), the length of the strings s and t. Each of the next two lines contains the strings s and t, each having length exactly n. The strings consist only of lowercase English letters. It is guaranteed that strings are different. Output For each test case, output "Yes" if Ujan can make the two strings equal and "No" otherwise. You can print each letter in any case (upper or lower). Example Input 4 5 souse houhe 3 cat dog 2 aa az 3 abc bca Output Yes No No No Note In the first test case, Ujan can swap characters s_1 and t_4, obtaining the word "house". In the second test case, it is not possible to make the strings equal using exactly one swap of s_i and t_j. Tags: strings Correct Solution: ``` tc = int(input()) for t in range(tc) : n = int(input()) s = [char for char in input()] t = [char for char in input()] freq = {} for i in range(n) : if s[i] in freq.keys() : freq[s[i]] += 1 else : freq[s[i]] = 1 if t[i] in freq.keys() : freq[t[i]] += 1 else : freq[t[i]] = 1 isPossible = True for key in freq.keys() : if freq[key] % 2 != 0 : isPossible = False if isPossible == False : print("No") continue print("Yes") moves = [] for i in range(n) : if s[i] == t[i] : continue else : found = False for j in range(i+1, n) : if s[j] == s[i] : moves.append((j, i)) s[j] = t[i] t[i] = s[i] found = True break if found : continue for j in range(i+1, n) : if t[j] == s[i] : moves.append((j, j)) temp = s[j] s[j] = t[j] t[j] = temp moves.append((j, i)) s[j] = t[i] t[i] = s[i] break print(len(moves)) for i, j in moves : print(str(i+1) + " " + str(j+1)) ```

Provide tags and a correct Python 3 solution for this coding contest problem. This problem is different from the hard version. In this version Ujan makes exactly one exchange. You can hack this problem only if you solve both problems. After struggling and failing many times, Ujan decided to try to clean up his house again. He decided to get his strings in order first. Ujan has two distinct strings s and t of length n consisting of only of lowercase English characters. He wants to make them equal. Since Ujan is lazy, he will perform the following operation exactly once: he takes two positions i and j (1 ≤ i,j ≤ n, the values i and j can be equal or different), and swaps the characters s_i and t_j. Can he succeed? Note that he has to perform this operation exactly once. He has to perform this operation. Input The first line contains a single integer k (1 ≤ k ≤ 10), the number of test cases. For each of the test cases, the first line contains a single integer n (2 ≤ n ≤ 10^4), the length of the strings s and t. Each of the next two lines contains the strings s and t, each having length exactly n. The strings consist only of lowercase English letters. It is guaranteed that strings are different. Output For each test case, output "Yes" if Ujan can make the two strings equal and "No" otherwise. You can print each letter in any case (upper or lower). Example Input 4 5 souse houhe 3 cat dog 2 aa az 3 abc bca Output Yes No No No Note In the first test case, Ujan can swap characters s_1 and t_4, obtaining the word "house". In the second test case, it is not possible to make the strings equal using exactly one swap of s_i and t_j. Tags: strings Correct Solution: ``` for _ in range(int(input())): n=int(input()) a=list(input()) b=list(input()) ans=[] d1=dict() d2=dict() for i in range(n): try: d1[a[i]].add(i) except: d1[a[i]]=set([(i)]) try: d2[b[i]].add(i) except: d2[b[i]]=set([i]) # print(d1) f1=0 count=0 for i in range(n): d1[a[i]].remove(i) d2[b[i]].remove(i) if a[i]!=b[i]: flag=0 for j in d1[a[i]]: if a[j]!=b[j] : ans.append([j+1,i+1]) count+=1 d1[a[j]].remove(j) a[j],b[i]=b[i],a[j] try: d1[a[j]].add(j) except: d1[a[j]]=set([(j)]) try: d2[b[j]].add(j) except: d2[b[j]]=set([j]) flag=1 break if flag==0: if a[i] in d2: for j in d2[a[i]]: if a[j]!=b[j]: ans.append([j+1,j+1]) d1[a[j]].remove(j) d2[b[j]].remove(j) a[j],b[j]=b[j],a[j] count+=2 # print(a,b) try: d1[a[j]].add(j) except: d1[a[j]]=set([(j)]) try: d2[b[j]].add(j) except: d2[b[j]]=set([j]) d1[a[j]].remove(j) ans.append([j+1,i+1]) a[j],b[i]=b[i],a[j] # print(i,j,a,b) try: d1[a[j]].add(j) except: d1[a[j]]=set([(j)]) try: d2[b[j]].add(j) except: d2[b[j]]=set([j]) flag=1 break if flag==0 or count>1: f1=1 break if f1==0: print("Yes") # print(len(ans)) #for i in ans: # print(*i) else: print("No") # print(a) # print(b) ```

Provide tags and a correct Python 3 solution for this coding contest problem. This problem is different from the hard version. In this version Ujan makes exactly one exchange. You can hack this problem only if you solve both problems. After struggling and failing many times, Ujan decided to try to clean up his house again. He decided to get his strings in order first. Ujan has two distinct strings s and t of length n consisting of only of lowercase English characters. He wants to make them equal. Since Ujan is lazy, he will perform the following operation exactly once: he takes two positions i and j (1 ≤ i,j ≤ n, the values i and j can be equal or different), and swaps the characters s_i and t_j. Can he succeed? Note that he has to perform this operation exactly once. He has to perform this operation. Input The first line contains a single integer k (1 ≤ k ≤ 10), the number of test cases. For each of the test cases, the first line contains a single integer n (2 ≤ n ≤ 10^4), the length of the strings s and t. Each of the next two lines contains the strings s and t, each having length exactly n. The strings consist only of lowercase English letters. It is guaranteed that strings are different. Output For each test case, output "Yes" if Ujan can make the two strings equal and "No" otherwise. You can print each letter in any case (upper or lower). Example Input 4 5 souse houhe 3 cat dog 2 aa az 3 abc bca Output Yes No No No Note In the first test case, Ujan can swap characters s_1 and t_4, obtaining the word "house". In the second test case, it is not possible to make the strings equal using exactly one swap of s_i and t_j. Tags: strings Correct Solution: ``` k = int(input()) for _ in range(k): n = int(input()) s = list(input().strip()) t = list(input().strip()) d = {} for i in range(n): if s[i]!=t[i]: try: d[(s[i],t[i])] += 1 except: d[(s[i],t[i])] = 1 if len(d)==1 and list(d.values())[0]==2: print('Yes') else: print('No') ```

Provide tags and a correct Python 3 solution for this coding contest problem. This problem is different from the hard version. In this version Ujan makes exactly one exchange. You can hack this problem only if you solve both problems. After struggling and failing many times, Ujan decided to try to clean up his house again. He decided to get his strings in order first. Ujan has two distinct strings s and t of length n consisting of only of lowercase English characters. He wants to make them equal. Since Ujan is lazy, he will perform the following operation exactly once: he takes two positions i and j (1 ≤ i,j ≤ n, the values i and j can be equal or different), and swaps the characters s_i and t_j. Can he succeed? Note that he has to perform this operation exactly once. He has to perform this operation. Input The first line contains a single integer k (1 ≤ k ≤ 10), the number of test cases. For each of the test cases, the first line contains a single integer n (2 ≤ n ≤ 10^4), the length of the strings s and t. Each of the next two lines contains the strings s and t, each having length exactly n. The strings consist only of lowercase English letters. It is guaranteed that strings are different. Output For each test case, output "Yes" if Ujan can make the two strings equal and "No" otherwise. You can print each letter in any case (upper or lower). Example Input 4 5 souse houhe 3 cat dog 2 aa az 3 abc bca Output Yes No No No Note In the first test case, Ujan can swap characters s_1 and t_4, obtaining the word "house". In the second test case, it is not possible to make the strings equal using exactly one swap of s_i and t_j. Tags: strings Correct Solution: ``` for i in range(int(input())): n=int(input()) s1=list(input()) s2=list(input()) ans="No" x=-1 for j in range(n): if(s1[j]!=s2[j]): x=j break if(x==-1): a=[0]*26 b=[0]*26 for j in range(n): a[ord(s1[j])-97]+=1 b[ord(s2[j])-97]+=1 for j in range(26): if(a[j]>1): ans="Yes" print(ans) else: aa="" bb="" for j in range(n): if(s1[j]!=s2[j]): aa+=s1[j] bb+=s2[j] if(len(aa)==2): if(aa[0]==aa[1] and bb[0]==bb[1]): print("Yes") else: print("No") else: print("No") ```

Provide tags and a correct Python 3 solution for this coding contest problem. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO".

Provide tags and a correct Python 3 solution for this coding contest problem. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO". Tags: implementation Correct Solution: ``` from sys import stdin read = stdin.readline n,k = map(int,read().split()) r = 0 vowel = {'a','e','i','o','u'} def cmp(a,b,k,vowel): l = 0 for x,y in zip(reversed(a),reversed(b)): if x != y: return False l += (x in vowel) if l == k: return True return False im = True for s in range(n): a,b,c,d = read(),read(),read(),read() l = 0 for i,x in enumerate(reversed(a),start=1): l += (x in vowel) if l == k: break else: print('NO') break b2,b3,b4 = (a[-i:] == b[-i:]),(a[-i:] == c[-i:]),(a[-i:] == d[-i:]) if b2 + b3 + b4 == 3: continue elif b2 + b3 + b4 == 1: if b2 and (r == 1 or r == 0) and cmp(c,d,k,vowel): r = 1 continue elif b3 and (r==2 or r == 0) and cmp(b,d,k,vowel): r = 2 continue elif b4 and (r == 3 or r == 0) and cmp(b,c,k,vowel): r = 3 continue print('NO') break else: print(['aaaa','aabb','abab','abba'][r]) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO". Tags: implementation Correct Solution: ``` n, k = map(int, input().split()) def get_suffix(line): position = 0 for _ in range(k): position -= 1 while -position <= len(line) and line[position] not in 'aeiou': position -= 1 if -position > len(line): return '' return line[position:] common_rhyme_type = 'aaaa' for _ in range(n): s1, s2, s3, s4 = [get_suffix(input()) for _ in range(4)] if '' in (s1, s2, s3, s4): print('NO') break if s1 == s2 == s3 == s4: rhyme_type = 'aaaa' elif s1 == s2 and s3 == s4: rhyme_type = 'aabb' elif s1 == s3 and s2 == s4: rhyme_type = 'abab' elif s1 == s4 and s2 == s3: rhyme_type = 'abba' else: print('NO') break if rhyme_type != 'aaaa': if common_rhyme_type != 'aaaa' and rhyme_type != common_rhyme_type: print('NO') break else: common_rhyme_type = rhyme_type else: print(common_rhyme_type) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO". Tags: implementation Correct Solution: ``` n, k = map(int, input().split()) ve = 'aeiou' abba, aabb, abab = 1, 1, 1 for j in range(n): a = ['']*4 for i in range(4): a[i] = input() l = len(a[i]) curr = 0 while l > 0 and curr < k: l -= 1 if a[i][l] in ve: curr += 1 if curr == k: a[i] = a[i][l:] else: a[i] = str(i) if a[0] == a[3] and a[1] == a[2]: abba = abba and 1 else: abba = 0 if a[0] == a[1] and a[2] == a[3]: aabb = aabb and 1 else: aabb = 0 if a[0] == a[2] and a[1] == a[3]: abab = abab and 1 else: abab = 0 if abba and aabb and abab: print('aaaa') elif not(abba or aabb or abab): print('NO') elif abba: print('abba') elif abab: print('abab') elif aabb: print('aabb') # Made By Mostafa_Khaled ```

Provide tags and a correct Python 3 solution for this coding contest problem. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO". Tags: implementation Correct Solution: ``` n,k=list(map(int,input().split())) l=[] for i in range(4*n): l.append(input()) poss=0 lst=[] for i in l: c=0 n=len(i) for j in range(n-1,-1,-1): if(i[j]=='a' or i[j]=='e' or i[j]=='i' or i[j]=='o' or i[j]=='u'): c+=1 else: continue if(c==k): lst.append(i[j:]) break if(c<k): poss=1; break; if(poss==1): print("NO") else: n=len(lst) ch=[] ans=-1 pos=0 for i in range(0,n,4): s1=lst[i] s2=lst[i+1]; s3=lst[i+2]; s4=lst[i+3]; if(s1==s2 and s2==s3 and s3==s4): ch.append([1,2,3,4]) elif(s1!=s2): if(s1==s3 and s2==s4): ch.append([2]) if(ans!=-1 and ans!=2): pos=1; break ans=2 elif(s1==s4 and s2==s3): ch.append([3]) if(ans!=-1 and ans!=3): pos=1; break ans=3 else: pos=1; break else: if(s3==s4): ch.append([1]) if(ans!=-1 and ans!=1): pos=1; break ans=1 else: pos=1; break if(pos==1): print("NO") else: if(ans==-1): print("aaaa") elif(ans==2): print("abab") elif(ans==3): print("abba") elif(ans==1): print("aabb") ```

Provide tags and a correct Python 3 solution for this coding contest problem. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO".

Provide tags and a correct Python 3 solution for this coding contest problem. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO". Tags: implementation Correct Solution: ``` n, k = map(int, input().split()) ve = 'aeiou' abba, aabb, abab = 1, 1, 1 for j in range(n): a = ['']*4 for i in range(4): a[i] = input() l = len(a[i]) curr = 0 while l > 0 and curr < k: l -= 1 if a[i][l] in ve: curr += 1 if curr == k: a[i] = a[i][l:] else: a[i] = str(i) if a[0] == a[3] and a[1] == a[2]: abba = abba and 1 else: abba = 0 if a[0] == a[1] and a[2] == a[3]: aabb = aabb and 1 else: aabb = 0 if a[0] == a[2] and a[1] == a[3]: abab = abab and 1 else: abab = 0 if abba and aabb and abab: print('aaaa') elif not(abba or aabb or abab): print('NO') elif abba: print('abba') elif abab: print('abab') elif aabb: print('aabb') ```

Provide tags and a correct Python 3 solution for this coding contest problem. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO".

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO". Submitted Solution: ``` def s(l, k): v = 0 for i in range(len(l) - 1, -1, -1): if l[i] in 'aeiou': v += 1 if v == k: return l[i:] return '' def f(q): if '' in q: return 'NO' elif q[0] == q[1]: if q[2] == q[3]: return 'aaaa' if q[1] == q[2] else 'aabb' else: return 'NO' elif q[0] == q[2] and q[1] == q[3]: return 'abab' elif q[0] == q[3] and q[1] == q[2]: return 'abba' else: return 'NO' n, k = map(int, input().split()) v = '' for i in range(n): c = f([s(input(), k) for i in range(4)]) if c == 'NO': v = c break elif v and c in (v, 'aaaa'): pass elif v in ('', 'aaaa'): v = c else: v = 'NO' break print(v) ``` Yes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO".

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO". Submitted Solution: ``` n, k = map(int, input().split()) vowels = ['a', 'e', 'i', 'o', 'u'] def find_nth(tab, S, n): amount, pos = (1 if tab[0] in S else 0), 0 while pos < len(tab) and amount < n: pos += 1 if tab[pos] in S: amount += 1 return pos def rhyme_type(lines, k): suffixes = [] for line in lines: amount = 0 for i in line: if i in vowels: amount += 1 if amount < k: return 'TRASH' rev = list(reversed(list(line))) ind_from_front = find_nth(rev, vowels, k) suffixes.append(line[-ind_from_front - 1:]) if all([suffixes[0] == x for x in suffixes]): return 'aaaa' if suffixes[0] == suffixes[1] and suffixes[2] == suffixes[3]: return 'aabb' if suffixes[0] == suffixes[2] and suffixes[1] == suffixes[3]: return 'abab' if suffixes[0] == suffixes[3] and suffixes[1] == suffixes[2]: return 'abba' return 'TRASH' all_rhymes = set() for _ in range(n): lines = [input(), input(), input(), input()] all_rhymes.add(rhyme_type(lines, k)) if 'TRASH' not in all_rhymes and len(all_rhymes) == 2 and 'aaaa' in all_rhymes: all_rhymes.remove('aaaa') print(list(all_rhymes)[0]) elif len(all_rhymes) > 1 or 'TRASH' in all_rhymes: print('NO') else: print(list(all_rhymes)[0]) ``` Yes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO".

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO".

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO". Submitted Solution: ``` n,k = map(int,input().split()) lis=[] vov=['a','e','i','o','u'] d={} d['aabb']=d['abab']=d['abba']=d['aaaa']=0 for i in range(n*4): s = input() lis.append(s) if i%4==3: tmp=['']*4 for j in range(4): s=lis[j] c=0 cou=0 for ll in s[::-1]: cou+=1 if ll in vov: c+=1 if c==k: tmp[j]=s[-cou:] break if tmp[0]==tmp[1]==tmp[2]==tmp[3] and tmp[0]!='': d['aaaa']+=1 if tmp[0]==tmp[1] and tmp[2]==tmp[3] and tmp[1]!=tmp[3] and tmp[1]!='' and tmp[3]!='': d['aabb']+=1 elif tmp[0]==tmp[2] and tmp[1]==tmp[3] and tmp[1]!=tmp[0] and tmp[1]!='' and tmp[0]!='': d['abab']+=1 elif tmp[0]==tmp[3] and tmp[1]==tmp[2] and tmp[2]!=tmp[0] and tmp[1]!='' and tmp[3]!='': d['abba']+=1 lis=[] c=0 for i in d: if d[i]>0: c+=1 if c==1: for i in d: if d[i]>0: print(i) exit() elif c==2 and d['aaaa']>0: for i in d: if d[i]>0: print(i) exit() else: print(-1) ``` No

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO". Submitted Solution: ``` n,k=map(int,input().split()) vowel=["a","e","i","o","u"] w="";t=0;change=0; for i in range (4*n) : x=input() #print(x,change) j=x[::-1] #l.append(x) count=0;t=0; for i in j: t=t+1 if i in vowel : count=count+1 if (count==k) : break #print(x,count) if (count!=k) : exit(print("NO")) if j[:t]==w : w=j[:t] else : change=change+1 w=j[:t] if (change>4) : exit(print("NO")) if (change==1 ) : print("aaaa") elif (change==2 ) : print("aabb") elif (change==3) : print("abba") else : print("abab") ``` No

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Vera adores poems. All the poems Vera knows are divided into quatrains (groups of four lines) and in each quatrain some lines contain rhymes. Let's consider that all lines in the poems consist of lowercase Latin letters (without spaces). Letters "a", "e", "i", "o", "u" are considered vowels. Two lines rhyme if their suffixes that start from the k-th vowels (counting from the end) match. If a line has less than k vowels, then such line can't rhyme with any other line. For example, if k = 1, lines commit and hermit rhyme (the corresponding suffixes equal it), and if k = 2, they do not rhyme (ommit ≠ ermit). Today on a literature lesson Vera learned that quatrains can contain four different schemes of rhymes, namely the following ones (the same letters stand for rhyming lines): * Clerihew (aabb); * Alternating (abab); * Enclosed (abba). If all lines of a quatrain pairwise rhyme, then the quatrain can belong to any rhyme scheme (this situation is represented by aaaa). If all quatrains of a poem belong to the same rhyme scheme, then we can assume that the whole poem belongs to this rhyme scheme. If in each quatrain all lines pairwise rhyme, then the rhyme scheme of the poem is aaaa. Let us note that it doesn't matter whether lines from different quatrains rhyme with each other or not. In other words, it is possible that different quatrains aren't connected by a rhyme. Vera got a long poem as a home task. The girl has to analyse it and find the poem rhyme scheme. Help Vera cope with the task. Input The first line contains two integers n and k (1 ≤ n ≤ 2500, 1 ≤ k ≤ 5) — the number of quatrains in the poem and the vowel's number, correspondingly. Next 4n lines contain the poem. Each line is not empty and only consists of small Latin letters. The total length of the lines does not exceed 104. If we assume that the lines are numbered starting from 1, then the first quatrain contains lines number 1, 2, 3, 4; the second one contains lines number 5, 6, 7, 8; and so on. Output Print the rhyme scheme of the poem as "aabb", "abab", "abba", "aaaa"; or "NO" if the poem does not belong to any of the above mentioned schemes. Examples Input 1 1 day may sun fun Output aabb Input 1 1 day may gray way Output aaaa Input 2 1 a a a a a a e e Output aabb Input 2 1 day may sun fun test hill fest thrill Output NO Note In the last sample both quatrains have rhymes but finding the common scheme is impossible, so the answer is "NO".

Provide a correct Python 3 solution for this coding contest problem. Stylish is a programming language whose syntax comprises names, that are sequences of Latin alphabet letters, three types of grouping symbols, periods ('.'), and newlines. Grouping symbols, namely round brackets ('(' and ')'), curly brackets ('{' and '}'), and square brackets ('[' and ']'), must match and be nested properly. Unlike most other programming languages, Stylish uses periods instead of whitespaces for the purpose of term separation. The following is an example of a Stylish program. 1 ( Welcome .to 2 ......... Stylish ) 3 { Stylish .is 4 .....[.( a. programming . language .fun .to. learn ) 5 .......] 6 ..... Maybe .[ 7 ....... It. will .be.an. official . ICPC . language 8 .......] 9 .....} As you see in the example, a Stylish program is indented by periods. The amount of indentation of a line is the number of leading periods of it. Your mission is to visit Stylish masters, learn their indentation styles, and become the youngest Stylish master. An indentation style for well-indented Stylish programs is defined by a triple of integers, (R, C, S), satisfying 1 ≤ R, C, S ≤ 20. R, C and S are amounts of indentation introduced by an open round bracket, an open curly bracket, and an open square bracket, respectively. In a well-indented program, the amount of indentation of a line is given by R(ro − rc) + C(co − cc) + S(so − sc), where ro, co, and so are the numbers of occurrences of open round, curly, and square brackets in all preceding lines, respectively, and rc, cc, and sc are those of close brackets. The first line has no indentation in any well-indented program. The above example is formatted in the indentation style (R, C, S) = (9, 5, 2). The only grouping symbol occurring in the first line of the above program is an open round bracket. Therefore the amount of indentation for the second line is 9 * (1 − 0) + 5 * (0 − 0) + 2 *(0 − 0) = 9. The first four lines contain two open round brackets, one open curly bracket, one open square bracket, two close round brackets, but no close curly nor square bracket. Therefore the amount of indentation for the fifth line is 9 * (2 − 2) + 5 * (1 − 0) + 2 * (1 − 0) = 7. Stylish masters write only well-indented Stylish programs. Every master has his/her own indentation style. Write a program that imitates indentation styles of Stylish masters. Input The input consists of multiple datasets. The first line of a dataset contains two integers p (1 ≤ p ≤ 10) and q (1 ≤ q ≤ 10). The next p lines form a well-indented program P written by a Stylish master and the following q lines form another program Q. You may assume that every line of both programs has at least one character and at most 80 characters. Also, you may assume that no line of Q starts with a period. The last dataset is followed by a line containing two zeros. Output Apply the indentation style of P to Q and output the appropriate amount of indentation for each line of Q. The amounts must be output in a line in the order of corresponding lines of Q and they must be separated by a single space. The last one should not be followed by trailing spaces. If the appropriate amount of indentation of a line of Q cannot be determined uniquely through analysis of P, then output -1 for that line.

Provide a correct Python 3 solution for this coding contest problem. Stylish is a programming language whose syntax comprises names, that are sequences of Latin alphabet letters, three types of grouping symbols, periods ('.'), and newlines. Grouping symbols, namely round brackets ('(' and ')'), curly brackets ('{' and '}'), and square brackets ('[' and ']'), must match and be nested properly. Unlike most other programming languages, Stylish uses periods instead of whitespaces for the purpose of term separation. The following is an example of a Stylish program. 1 ( Welcome .to 2 ......... Stylish ) 3 { Stylish .is 4 .....[.( a. programming . language .fun .to. learn ) 5 .......] 6 ..... Maybe .[ 7 ....... It. will .be.an. official . ICPC . language 8 .......] 9 .....} As you see in the example, a Stylish program is indented by periods. The amount of indentation of a line is the number of leading periods of it. Your mission is to visit Stylish masters, learn their indentation styles, and become the youngest Stylish master. An indentation style for well-indented Stylish programs is defined by a triple of integers, (R, C, S), satisfying 1 ≤ R, C, S ≤ 20. R, C and S are amounts of indentation introduced by an open round bracket, an open curly bracket, and an open square bracket, respectively. In a well-indented program, the amount of indentation of a line is given by R(ro − rc) + C(co − cc) + S(so − sc), where ro, co, and so are the numbers of occurrences of open round, curly, and square brackets in all preceding lines, respectively, and rc, cc, and sc are those of close brackets. The first line has no indentation in any well-indented program. The above example is formatted in the indentation style (R, C, S) = (9, 5, 2). The only grouping symbol occurring in the first line of the above program is an open round bracket. Therefore the amount of indentation for the second line is 9 * (1 − 0) + 5 * (0 − 0) + 2 *(0 − 0) = 9. The first four lines contain two open round brackets, one open curly bracket, one open square bracket, two close round brackets, but no close curly nor square bracket. Therefore the amount of indentation for the fifth line is 9 * (2 − 2) + 5 * (1 − 0) + 2 * (1 − 0) = 7. Stylish masters write only well-indented Stylish programs. Every master has his/her own indentation style. Write a program that imitates indentation styles of Stylish masters. Input The input consists of multiple datasets. The first line of a dataset contains two integers p (1 ≤ p ≤ 10) and q (1 ≤ q ≤ 10). The next p lines form a well-indented program P written by a Stylish master and the following q lines form another program Q. You may assume that every line of both programs has at least one character and at most 80 characters. Also, you may assume that no line of Q starts with a period. The last dataset is followed by a line containing two zeros. Output Apply the indentation style of P to Q and output the appropriate amount of indentation for each line of Q. The amounts must be output in a line in the order of corresponding lines of Q and they must be separated by a single space. The last one should not be followed by trailing spaces. If the appropriate amount of indentation of a line of Q cannot be determined uniquely through analysis of P, then output -1 for that line.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Stylish is a programming language whose syntax comprises names, that are sequences of Latin alphabet letters, three types of grouping symbols, periods ('.'), and newlines. Grouping symbols, namely round brackets ('(' and ')'), curly brackets ('{' and '}'), and square brackets ('[' and ']'), must match and be nested properly. Unlike most other programming languages, Stylish uses periods instead of whitespaces for the purpose of term separation. The following is an example of a Stylish program. 1 ( Welcome .to 2 ......... Stylish ) 3 { Stylish .is 4 .....[.( a. programming . language .fun .to. learn ) 5 .......] 6 ..... Maybe .[ 7 ....... It. will .be.an. official . ICPC . language 8 .......] 9 .....} As you see in the example, a Stylish program is indented by periods. The amount of indentation of a line is the number of leading periods of it. Your mission is to visit Stylish masters, learn their indentation styles, and become the youngest Stylish master. An indentation style for well-indented Stylish programs is defined by a triple of integers, (R, C, S), satisfying 1 ≤ R, C, S ≤ 20. R, C and S are amounts of indentation introduced by an open round bracket, an open curly bracket, and an open square bracket, respectively. In a well-indented program, the amount of indentation of a line is given by R(ro − rc) + C(co − cc) + S(so − sc), where ro, co, and so are the numbers of occurrences of open round, curly, and square brackets in all preceding lines, respectively, and rc, cc, and sc are those of close brackets. The first line has no indentation in any well-indented program. The above example is formatted in the indentation style (R, C, S) = (9, 5, 2). The only grouping symbol occurring in the first line of the above program is an open round bracket. Therefore the amount of indentation for the second line is 9 * (1 − 0) + 5 * (0 − 0) + 2 *(0 − 0) = 9. The first four lines contain two open round brackets, one open curly bracket, one open square bracket, two close round brackets, but no close curly nor square bracket. Therefore the amount of indentation for the fifth line is 9 * (2 − 2) + 5 * (1 − 0) + 2 * (1 − 0) = 7. Stylish masters write only well-indented Stylish programs. Every master has his/her own indentation style. Write a program that imitates indentation styles of Stylish masters. Input The input consists of multiple datasets. The first line of a dataset contains two integers p (1 ≤ p ≤ 10) and q (1 ≤ q ≤ 10). The next p lines form a well-indented program P written by a Stylish master and the following q lines form another program Q. You may assume that every line of both programs has at least one character and at most 80 characters. Also, you may assume that no line of Q starts with a period. The last dataset is followed by a line containing two zeros. Output Apply the indentation style of P to Q and output the appropriate amount of indentation for each line of Q. The amounts must be output in a line in the order of corresponding lines of Q and they must be separated by a single space. The last one should not be followed by trailing spaces. If the appropriate amount of indentation of a line of Q cannot be determined uniquely through analysis of P, then output -1 for that line.

Provide tags and a correct Python 3 solution for this coding contest problem. R3D3 spent some time on an internship in MDCS. After earning enough money, he decided to go on a holiday somewhere far, far away. He enjoyed suntanning, drinking alcohol-free cocktails and going to concerts of popular local bands. While listening to "The White Buttons" and their hit song "Dacan the Baker", he met another robot for whom he was sure is the love of his life. Well, his summer, at least. Anyway, R3D3 was too shy to approach his potential soulmate, so he decided to write her a love letter. However, he stumbled upon a problem. Due to a terrorist threat, the Intergalactic Space Police was monitoring all letters sent in the area. Thus, R3D3 decided to invent his own alphabet, for which he was sure his love would be able to decipher. There are n letters in R3D3’s alphabet, and he wants to represent each letter as a sequence of '0' and '1', so that no letter’s sequence is a prefix of another letter's sequence. Since the Intergalactic Space Communications Service has lately introduced a tax for invented alphabets, R3D3 must pay a certain amount of money for each bit in his alphabet’s code (check the sample test for clarifications). He is too lovestruck to think clearly, so he asked you for help. Given the costs c0 and c1 for each '0' and '1' in R3D3’s alphabet, respectively, you should come up with a coding for the alphabet (with properties as above) with minimum total cost. Input The first line of input contains three integers n (2 ≤ n ≤ 108), c0 and c1 (0 ≤ c0, c1 ≤ 108) — the number of letters in the alphabet, and costs of '0' and '1', respectively. Output Output a single integer — minimum possible total a cost of the whole alphabet. Example Input 4 1 2 Output 12 Note There are 4 letters in the alphabet. The optimal encoding is "00", "01", "10", "11". There are 4 zeroes and 4 ones used, so the total cost is 4·1 + 4·2 = 12. Tags: dp, greedy Correct Solution: ``` import sys,heapq #sys.stdin=open("data.txt") input=sys.stdin.readline n,a,b=map(int,input().split()) if a<b: a,b=b,a if b==0: # 1 01 001 0001 ... is optimal, plus a long series of 0's print((n-1)*a) else: # pascal's triangle thing pascal=[[1]*20005] for i in range(20004): newrow=[1] for j in range(1,20005): newrow.append(newrow[-1]+pascal[-1][j]) if newrow[-1]>n: break pascal.append(newrow) def getcom(a,b): # return a+b choose b # if larger than n, return infinite if len(pascal[a])>b: return pascal[a][b] if b==0: return 1 if b==1: return a return 100000005 # start with the null node (prefix cost 0) # can split a node into two other nodes with added cost c+a+b # new nodes have prefix costs c+a, c+b # want n-1 splits in total remain=n-1 ans=0 possible=[[a+b,1]] # [c,count] while 1: # cost u, v leaves u,v=heapq.heappop(possible) while possible and possible[0][0]==u: v+=possible[0][1] heapq.heappop(possible) if remain<=v: ans+=u*remain break ans+=u*v remain-=v heapq.heappush(possible,[u+a,v]) heapq.heappush(possible,[u+b,v]) print(ans) # Made By Mostafa_Khaled ```

Provide tags and a correct Python 3 solution for this coding contest problem. R3D3 spent some time on an internship in MDCS. After earning enough money, he decided to go on a holiday somewhere far, far away. He enjoyed suntanning, drinking alcohol-free cocktails and going to concerts of popular local bands. While listening to "The White Buttons" and their hit song "Dacan the Baker", he met another robot for whom he was sure is the love of his life. Well, his summer, at least. Anyway, R3D3 was too shy to approach his potential soulmate, so he decided to write her a love letter. However, he stumbled upon a problem. Due to a terrorist threat, the Intergalactic Space Police was monitoring all letters sent in the area. Thus, R3D3 decided to invent his own alphabet, for which he was sure his love would be able to decipher. There are n letters in R3D3’s alphabet, and he wants to represent each letter as a sequence of '0' and '1', so that no letter’s sequence is a prefix of another letter's sequence. Since the Intergalactic Space Communications Service has lately introduced a tax for invented alphabets, R3D3 must pay a certain amount of money for each bit in his alphabet’s code (check the sample test for clarifications). He is too lovestruck to think clearly, so he asked you for help. Given the costs c0 and c1 for each '0' and '1' in R3D3’s alphabet, respectively, you should come up with a coding for the alphabet (with properties as above) with minimum total cost. Input The first line of input contains three integers n (2 ≤ n ≤ 108), c0 and c1 (0 ≤ c0, c1 ≤ 108) — the number of letters in the alphabet, and costs of '0' and '1', respectively. Output Output a single integer — minimum possible total a cost of the whole alphabet. Example Input 4 1 2 Output 12 Note There are 4 letters in the alphabet. The optimal encoding is "00", "01", "10", "11". There are 4 zeroes and 4 ones used, so the total cost is 4·1 + 4·2 = 12.

Provide tags and a correct Python 3 solution for this coding contest problem. R3D3 spent some time on an internship in MDCS. After earning enough money, he decided to go on a holiday somewhere far, far away. He enjoyed suntanning, drinking alcohol-free cocktails and going to concerts of popular local bands. While listening to "The White Buttons" and their hit song "Dacan the Baker", he met another robot for whom he was sure is the love of his life. Well, his summer, at least. Anyway, R3D3 was too shy to approach his potential soulmate, so he decided to write her a love letter. However, he stumbled upon a problem. Due to a terrorist threat, the Intergalactic Space Police was monitoring all letters sent in the area. Thus, R3D3 decided to invent his own alphabet, for which he was sure his love would be able to decipher. There are n letters in R3D3’s alphabet, and he wants to represent each letter as a sequence of '0' and '1', so that no letter’s sequence is a prefix of another letter's sequence. Since the Intergalactic Space Communications Service has lately introduced a tax for invented alphabets, R3D3 must pay a certain amount of money for each bit in his alphabet’s code (check the sample test for clarifications). He is too lovestruck to think clearly, so he asked you for help. Given the costs c0 and c1 for each '0' and '1' in R3D3’s alphabet, respectively, you should come up with a coding for the alphabet (with properties as above) with minimum total cost. Input The first line of input contains three integers n (2 ≤ n ≤ 108), c0 and c1 (0 ≤ c0, c1 ≤ 108) — the number of letters in the alphabet, and costs of '0' and '1', respectively. Output Output a single integer — minimum possible total a cost of the whole alphabet. Example Input 4 1 2 Output 12 Note There are 4 letters in the alphabet. The optimal encoding is "00", "01", "10", "11". There are 4 zeroes and 4 ones used, so the total cost is 4·1 + 4·2 = 12. Tags: dp, greedy Correct Solution: ``` import sys,heapq #sys.stdin=open("data.txt") input=sys.stdin.readline n,a,b=map(int,input().split()) if a<b: a,b=b,a if b==0: # 1 01 001 0001 ... is optimal, plus a long series of 0's print((n-1)*a) else: # pascal's triangle thing pascal=[[1]*20005] for i in range(20004): newrow=[1] for j in range(1,20005): newrow.append(newrow[-1]+pascal[-1][j]) if newrow[-1]>n: break pascal.append(newrow) def getcom(a,b): # return a+b choose b # if larger than n, return infinite if len(pascal[a])>b: return pascal[a][b] if b==0: return 1 if b==1: return a return 100000005 # start with the null node (prefix cost 0) # can split a node into two other nodes with added cost c+a+b # new nodes have prefix costs c+a, c+b # want n-1 splits in total remain=n-1 ans=0 possible=[[a+b,1]] # [c,count] while 1: # cost u, v leaves u,v=heapq.heappop(possible) while possible and possible[0][0]==u: v+=possible[0][1] heapq.heappop(possible) if remain<=v: ans+=u*remain break ans+=u*v remain-=v heapq.heappush(possible,[u+a,v]) heapq.heappush(possible,[u+b,v]) print(ans) ```

Provide tags and a correct Python 3 solution for this coding contest problem. R3D3 spent some time on an internship in MDCS. After earning enough money, he decided to go on a holiday somewhere far, far away. He enjoyed suntanning, drinking alcohol-free cocktails and going to concerts of popular local bands. While listening to "The White Buttons" and their hit song "Dacan the Baker", he met another robot for whom he was sure is the love of his life. Well, his summer, at least. Anyway, R3D3 was too shy to approach his potential soulmate, so he decided to write her a love letter. However, he stumbled upon a problem. Due to a terrorist threat, the Intergalactic Space Police was monitoring all letters sent in the area. Thus, R3D3 decided to invent his own alphabet, for which he was sure his love would be able to decipher. There are n letters in R3D3’s alphabet, and he wants to represent each letter as a sequence of '0' and '1', so that no letter’s sequence is a prefix of another letter's sequence. Since the Intergalactic Space Communications Service has lately introduced a tax for invented alphabets, R3D3 must pay a certain amount of money for each bit in his alphabet’s code (check the sample test for clarifications). He is too lovestruck to think clearly, so he asked you for help. Given the costs c0 and c1 for each '0' and '1' in R3D3’s alphabet, respectively, you should come up with a coding for the alphabet (with properties as above) with minimum total cost. Input The first line of input contains three integers n (2 ≤ n ≤ 108), c0 and c1 (0 ≤ c0, c1 ≤ 108) — the number of letters in the alphabet, and costs of '0' and '1', respectively. Output Output a single integer — minimum possible total a cost of the whole alphabet. Example Input 4 1 2 Output 12 Note There are 4 letters in the alphabet. The optimal encoding is "00", "01", "10", "11". There are 4 zeroes and 4 ones used, so the total cost is 4·1 + 4·2 = 12. Tags: dp, greedy Correct Solution: ``` import sys,heapq #sys.stdin=open("data.txt") input=sys.stdin.readline n,a,b=map(int,input().split()) if a<b: a,b=b,a if b==0: # 1 01 001 0001 ... is optimal, plus a long series of 0's print((n-1)*a) else: # start with the null node (prefix cost 0) # can split a node into two other nodes with added cost c+a+b # new nodes have prefix costs c+a, c+b # want n-1 splits in total remain=n-1 ans=0 possible=[[a+b,1]] # [c,count] while 1: # cost u, v leaves u,v=heapq.heappop(possible) while possible and possible[0][0]==u: v+=possible[0][1] heapq.heappop(possible) if remain<=v: ans+=u*remain break ans+=u*v remain-=v heapq.heappush(possible,[u+a,v]) heapq.heappush(possible,[u+b,v]) print(ans) ```

Provide tags and a correct Python 3 solution for this coding contest problem. After overcoming the stairs Dasha came to classes. She needed to write a password to begin her classes. The password is a string of length n which satisfies the following requirements: * There is at least one digit in the string, * There is at least one lowercase (small) letter of the Latin alphabet in the string, * There is at least one of three listed symbols in the string: '#', '*', '&'. <image> Considering that these are programming classes it is not easy to write the password. For each character of the password we have a fixed string of length m, on each of these n strings there is a pointer on some character. The i-th character displayed on the screen is the pointed character in the i-th string. Initially, all pointers are on characters with indexes 1 in the corresponding strings (all positions are numbered starting from one). During one operation Dasha can move a pointer in one string one character to the left or to the right. Strings are cyclic, it means that when we move the pointer which is on the character with index 1 to the left, it moves to the character with the index m, and when we move it to the right from the position m it moves to the position 1. You need to determine the minimum number of operations necessary to make the string displayed on the screen a valid password. Input The first line contains two integers n, m (3 ≤ n ≤ 50, 1 ≤ m ≤ 50) — the length of the password and the length of strings which are assigned to password symbols. Each of the next n lines contains the string which is assigned to the i-th symbol of the password string. Its length is m, it consists of digits, lowercase English letters, and characters '#', '*' or '&'. You have such input data that you can always get a valid password. Output Print one integer — the minimum number of operations which is necessary to make the string, which is displayed on the screen, a valid password. Examples Input 3 4 1**2 a3*0 c4** Output 1 Input 5 5 #*&amp;#* *a1c&amp; &amp;q2w* #a3c# *&amp;#*&amp; Output 3 Note In the first test it is necessary to move the pointer of the third string to one left to get the optimal answer. <image> In the second test one of possible algorithms will be: * to move the pointer of the second symbol once to the right. * to move the pointer of the third symbol twice to the right. <image> Tags: brute force, dp, implementation Correct Solution: ``` import sys from itertools import permutations from operator import itemgetter def debug(x, table): for name, val in table.items(): if x is val: print('DEBUG:{} -> {}'.format(name, val), file=sys.stderr) return None INF = 1000 def solve(): n, m = map(int, input().split()) str_l = [] for i in range(n): moji = [] line = input() for c in line: if c == '*' or c == '#' or c == '&': moji.append('*') elif ord('0') <= ord(c) <= ord('9'): moji.append('1') else: moji.append('a') str_l.append(moji) # debug(str_l, locals()) row_nums = [] for i in range(n): kyori = [get_kyori(str_l[i], '1'), get_kyori(str_l[i], 'a'), get_kyori(str_l[i], '*')] row_nums.append(kyori) ans = INF debug(row_nums, locals()) for i, j, k in permutations((0,1,2)): tmp = 0 kyori_c = row_nums.copy() kyori_c.sort(key=itemgetter(i)) tmp += kyori_c[0][i] kyori_c = kyori_c[1:] kyori_c.sort(key=itemgetter(j)) tmp += kyori_c[0][j] kyori_c = kyori_c[1:] kyori_c.sort(key=itemgetter(k)) tmp += kyori_c[0][k] ans = min(tmp, ans) print(ans) def get_kyori(str1, c): res = INF if c in str1: i1 = str1.index(c) if i1 > len(str1) // 2: i1 = len(str1) - i1 i2 = len(str1) - str1[::-1].index(c) if i2 > len(str1) // 2: i2 = len(str1) - i2 + 1 res = min(i1, i2) return res if __name__ == '__main__': solve() ```

Provide tags and a correct Python 3 solution for this coding contest problem. After overcoming the stairs Dasha came to classes. She needed to write a password to begin her classes. The password is a string of length n which satisfies the following requirements: * There is at least one digit in the string, * There is at least one lowercase (small) letter of the Latin alphabet in the string, * There is at least one of three listed symbols in the string: '#', '*', '&'. <image> Considering that these are programming classes it is not easy to write the password. For each character of the password we have a fixed string of length m, on each of these n strings there is a pointer on some character. The i-th character displayed on the screen is the pointed character in the i-th string. Initially, all pointers are on characters with indexes 1 in the corresponding strings (all positions are numbered starting from one). During one operation Dasha can move a pointer in one string one character to the left or to the right. Strings are cyclic, it means that when we move the pointer which is on the character with index 1 to the left, it moves to the character with the index m, and when we move it to the right from the position m it moves to the position 1. You need to determine the minimum number of operations necessary to make the string displayed on the screen a valid password. Input The first line contains two integers n, m (3 ≤ n ≤ 50, 1 ≤ m ≤ 50) — the length of the password and the length of strings which are assigned to password symbols. Each of the next n lines contains the string which is assigned to the i-th symbol of the password string. Its length is m, it consists of digits, lowercase English letters, and characters '#', '*' or '&'. You have such input data that you can always get a valid password. Output Print one integer — the minimum number of operations which is necessary to make the string, which is displayed on the screen, a valid password. Examples Input 3 4 1**2 a3*0 c4** Output 1 Input 5 5 #*&amp;#* *a1c&amp; &amp;q2w* #a3c# *&amp;#*&amp; Output 3 Note In the first test it is necessary to move the pointer of the third string to one left to get the optimal answer. <image> In the second test one of possible algorithms will be: * to move the pointer of the second symbol once to the right. * to move the pointer of the third symbol twice to the right. <image> Tags: brute force, dp, implementation Correct Solution: ``` import itertools def transform_char(char): if char in ('#', '&', '*'): return '*' elif char.isdigit(): return '0' else: return 'a' def transform(string): ans = ''.join(transform_char(char) for char in string) return ans #input n, m = (int(x) for x in input().split()) symbols = [] for i in range(n): symbols.append(list(transform(input()))) sym1 = [ '#', '*', '&'] # sym2 = set(list('1234567890')) # sym3 = set(list(string.ascii_lowercase)) # print(len(sym3)) min_shifts = 10000 for permutation in itertools.permutations(symbols, 3): s1, s2, s3 = permutation sh1, sh2, sh3 = (100, 100, 100) for i in range((m + 2) // 2): if (s1[i] == '*' or s1[-i] == '*'): sh1 = min(sh1, i) if (s2[i] == '0' or s2[-i] == '0'): sh2 = min(sh2, i) if (s3[i] == 'a' or s3[-i] == 'a'): sh3 = min(sh3, i) min_shifts = min(min_shifts, (sh1 + sh2 + sh3)) print(min_shifts) ```

Provide tags and a correct Python 3 solution for this coding contest problem. After overcoming the stairs Dasha came to classes. She needed to write a password to begin her classes. The password is a string of length n which satisfies the following requirements: * There is at least one digit in the string, * There is at least one lowercase (small) letter of the Latin alphabet in the string, * There is at least one of three listed symbols in the string: '#', '*', '&'. <image> Considering that these are programming classes it is not easy to write the password. For each character of the password we have a fixed string of length m, on each of these n strings there is a pointer on some character. The i-th character displayed on the screen is the pointed character in the i-th string. Initially, all pointers are on characters with indexes 1 in the corresponding strings (all positions are numbered starting from one). During one operation Dasha can move a pointer in one string one character to the left or to the right. Strings are cyclic, it means that when we move the pointer which is on the character with index 1 to the left, it moves to the character with the index m, and when we move it to the right from the position m it moves to the position 1. You need to determine the minimum number of operations necessary to make the string displayed on the screen a valid password. Input The first line contains two integers n, m (3 ≤ n ≤ 50, 1 ≤ m ≤ 50) — the length of the password and the length of strings which are assigned to password symbols. Each of the next n lines contains the string which is assigned to the i-th symbol of the password string. Its length is m, it consists of digits, lowercase English letters, and characters '#', '*' or '&'. You have such input data that you can always get a valid password. Output Print one integer — the minimum number of operations which is necessary to make the string, which is displayed on the screen, a valid password. Examples Input 3 4 1**2 a3*0 c4** Output 1 Input 5 5 #*&amp;#* *a1c&amp; &amp;q2w* #a3c# *&amp;#*&amp; Output 3 Note In the first test it is necessary to move the pointer of the third string to one left to get the optimal answer. <image> In the second test one of possible algorithms will be: * to move the pointer of the second symbol once to the right. * to move the pointer of the third symbol twice to the right. <image> Tags: brute force, dp, implementation Correct Solution: ``` import itertools #input n, m = (int(x) for x in input().split()) symbols = [] for i in range(n): symbols.append(input()) sym1 = set([ '#', '*', '&']) sym2 = set(list('1234567890')) sym3 = set(list('qwertyuiopasdfghjklzxcvbnm')) # print(len(sym3)) min_shifts = 10000 for permutation in itertools.permutations(symbols, 3): s1, s2, s3 = permutation sh1, sh2, sh3 = (100, 100, 100) for i in range(m): if (s1[i] in sym1 or s1[-i] in sym1): sh1 = min(sh1, i) if (s2[i] in sym2 or s2[-i] in sym2): sh2 = min(sh2, i) if (s3[i] in sym3 or s3[-i] in sym3): sh3 = min(sh3, i) min_shifts = min(min_shifts, (sh1 + sh2 + sh3)) print(min_shifts) ```

Provide tags and a correct Python 3 solution for this coding contest problem. After overcoming the stairs Dasha came to classes. She needed to write a password to begin her classes. The password is a string of length n which satisfies the following requirements: * There is at least one digit in the string, * There is at least one lowercase (small) letter of the Latin alphabet in the string, * There is at least one of three listed symbols in the string: '#', '*', '&'. <image> Considering that these are programming classes it is not easy to write the password. For each character of the password we have a fixed string of length m, on each of these n strings there is a pointer on some character. The i-th character displayed on the screen is the pointed character in the i-th string. Initially, all pointers are on characters with indexes 1 in the corresponding strings (all positions are numbered starting from one). During one operation Dasha can move a pointer in one string one character to the left or to the right. Strings are cyclic, it means that when we move the pointer which is on the character with index 1 to the left, it moves to the character with the index m, and when we move it to the right from the position m it moves to the position 1. You need to determine the minimum number of operations necessary to make the string displayed on the screen a valid password. Input The first line contains two integers n, m (3 ≤ n ≤ 50, 1 ≤ m ≤ 50) — the length of the password and the length of strings which are assigned to password symbols. Each of the next n lines contains the string which is assigned to the i-th symbol of the password string. Its length is m, it consists of digits, lowercase English letters, and characters '#', '*' or '&'. You have such input data that you can always get a valid password. Output Print one integer — the minimum number of operations which is necessary to make the string, which is displayed on the screen, a valid password. Examples Input 3 4 1**2 a3*0 c4** Output 1 Input 5 5 #*&amp;#* *a1c&amp; &amp;q2w* #a3c# *&amp;#*&amp; Output 3 Note In the first test it is necessary to move the pointer of the third string to one left to get the optimal answer. <image> In the second test one of possible algorithms will be: * to move the pointer of the second symbol once to the right. * to move the pointer of the third symbol twice to the right. <image> Tags: brute force, dp, implementation Correct Solution: ``` n,m=map(int,input().split()) c=[list([])for i in range(3)] for i in range(n): t=input() s='' for i in range(m): if ord(t[i])<43:s+='1' elif ord(t[i])<59:s+='2' else: s+='3' x1=s.find('1') if s.find('1') != -1 else 60 x2=s[::-1].find('1')+1 if s.find('1') != -1 else 60 y1=s.find('2') if s.find('2') != -1 else 60 y2=s[::-1].find('2')+1 if s.find('2') != -1 else 60 z1=s.find('3') if s.find('3') != -1 else 60 z2=s[::-1].find('3')+1 if s.find('3') != -1 else 60 x,y,z=min(x1,x2),min(y1,y2),min(z1,z2) c[0].append(x) c[1].append(y) c[2].append(z) a=[list([])for i in range(3)] j=0 for i in c: for _ in range(3): t=min(i) s=i.index(t) c[j][s]=60 a[j].append([s,t]) j+=1 ans=10**10 for i in range(3): for j in range(3): for k in range(3): x,y,z=a[0][i],a[1][j],a[2][k] if len(set([x[0],y[0],z[0]]))!=3:continue ans=min(ans,x[1]+y[1]+z[1]) print(ans) ```

Provide tags and a correct Python 3 solution for this coding contest problem. After overcoming the stairs Dasha came to classes. She needed to write a password to begin her classes. The password is a string of length n which satisfies the following requirements: * There is at least one digit in the string, * There is at least one lowercase (small) letter of the Latin alphabet in the string, * There is at least one of three listed symbols in the string: '#', '*', '&'. <image> Considering that these are programming classes it is not easy to write the password. For each character of the password we have a fixed string of length m, on each of these n strings there is a pointer on some character. The i-th character displayed on the screen is the pointed character in the i-th string. Initially, all pointers are on characters with indexes 1 in the corresponding strings (all positions are numbered starting from one). During one operation Dasha can move a pointer in one string one character to the left or to the right. Strings are cyclic, it means that when we move the pointer which is on the character with index 1 to the left, it moves to the character with the index m, and when we move it to the right from the position m it moves to the position 1. You need to determine the minimum number of operations necessary to make the string displayed on the screen a valid password. Input The first line contains two integers n, m (3 ≤ n ≤ 50, 1 ≤ m ≤ 50) — the length of the password and the length of strings which are assigned to password symbols. Each of the next n lines contains the string which is assigned to the i-th symbol of the password string. Its length is m, it consists of digits, lowercase English letters, and characters '#', '*' or '&'. You have such input data that you can always get a valid password. Output Print one integer — the minimum number of operations which is necessary to make the string, which is displayed on the screen, a valid password. Examples Input 3 4 1**2 a3*0 c4** Output 1 Input 5 5 #*&amp;#* *a1c&amp; &amp;q2w* #a3c# *&amp;#*&amp; Output 3 Note In the first test it is necessary to move the pointer of the third string to one left to get the optimal answer. <image> In the second test one of possible algorithms will be: * to move the pointer of the second symbol once to the right. * to move the pointer of the third symbol twice to the right. <image> Tags: brute force, dp, implementation Correct Solution: ``` n, m = map(int, input().split()) a = [0] * n for i in range(n): a[i] = list(input()) g1 = '*#&' g2 = 'qwertyuiopasdfghjklzxcvbnm' g3 = '1234567890' b = [[-1] * 3 for i in range(n)] for i in range(n): f1, f2, f3 = 0, 0, 0 for j in range(m): if a[i][j] in g1 and f1 == 0: f1 = 1 b[i][0] = j elif a[i][j] in g2 and f2 == 0: f2 = 1 b[i][1] = j elif a[i][j] in g3 and f3 == 0: f3 = 1 b[i][2] = j f1, f2, f3 = 0, 0, 0 for j in range(-1, -1 * m, -1): if a[i][j] in g1 and f1 == 0: f1 = 1 b[i][0] = min(b[i][0], -1 * j ) elif a[i][j] in g2 and f2 == 0: f2 = 1 b[i][1] = min(b[i][1], -1 * j ) elif a[i][j] in g3 and f3 == 0: f3 = 1 b[i][2] = min(b[i][2], -1 * j) ans = int(1e9) for i in range(n): for j in range(n): for k in range(n): if i == j or j == k or i == k: continue #print(i, j, k) for l in range(3): for g in range(3): for q in range(3): if q != l and l != g and q != g and b[i][l] + b[j][g] + b[k][q] < ans and b[i][l] != -1 and b[j][g] != -1 and b[k][q] != -1: ans = b[i][l] + b[j][g] + b[k][q] #print(ans, i, j, k, l, g, q) print(ans) ```

Provide tags and a correct Python 3 solution for this coding contest problem. After overcoming the stairs Dasha came to classes. She needed to write a password to begin her classes. The password is a string of length n which satisfies the following requirements: * There is at least one digit in the string, * There is at least one lowercase (small) letter of the Latin alphabet in the string, * There is at least one of three listed symbols in the string: '#', '*', '&'. <image> Considering that these are programming classes it is not easy to write the password. For each character of the password we have a fixed string of length m, on each of these n strings there is a pointer on some character. The i-th character displayed on the screen is the pointed character in the i-th string. Initially, all pointers are on characters with indexes 1 in the corresponding strings (all positions are numbered starting from one). During one operation Dasha can move a pointer in one string one character to the left or to the right. Strings are cyclic, it means that when we move the pointer which is on the character with index 1 to the left, it moves to the character with the index m, and when we move it to the right from the position m it moves to the position 1. You need to determine the minimum number of operations necessary to make the string displayed on the screen a valid password. Input The first line contains two integers n, m (3 ≤ n ≤ 50, 1 ≤ m ≤ 50) — the length of the password and the length of strings which are assigned to password symbols. Each of the next n lines contains the string which is assigned to the i-th symbol of the password string. Its length is m, it consists of digits, lowercase English letters, and characters '#', '*' or '&'. You have such input data that you can always get a valid password. Output Print one integer — the minimum number of operations which is necessary to make the string, which is displayed on the screen, a valid password. Examples Input 3 4 1**2 a3*0 c4** Output 1 Input 5 5 #*&amp;#* *a1c&amp; &amp;q2w* #a3c# *&amp;#*&amp; Output 3 Note In the first test it is necessary to move the pointer of the third string to one left to get the optimal answer. <image> In the second test one of possible algorithms will be: * to move the pointer of the second symbol once to the right. * to move the pointer of the third symbol twice to the right. <image> Tags: brute force, dp, implementation Correct Solution: ``` n, m = [int(i) for i in input().split()] inf = 10 ** 18 fl = [inf] * n fn = [inf] * n fs = [inf] * n for i in range(n): s = input() for q in range(m): if s[q] >= '0' and s[q] <= '9' and fn[i] == inf: fn[i] = q if s[q] >= 'a' and s[q] <= 'z' and fl[i] == inf: fl[i] = q if s[q] in ['#', '*', '&'] and fs[i] == inf: fs[i] = q for q in range(m - 1, -1, -1): if s[q] >= '0' and s[q] <= '9': fn[i] = min(fn[i], m - q) if s[q] >= 'a' and s[q] <= 'z': fl[i] = min(fl[i], m - q) if s[q] in ['#', '*', '&']: fs[i] = min(fs[i], m - q) ans = inf for i in range(n): for q in range(n): if i == q: continue for j in range(n): if i == j or q == j: continue ans = min(ans, fn[i] + fl[q] + fs[j]) print(ans) ```

Provide tags and a correct Python 3 solution for this coding contest problem. After overcoming the stairs Dasha came to classes. She needed to write a password to begin her classes. The password is a string of length n which satisfies the following requirements: * There is at least one digit in the string, * There is at least one lowercase (small) letter of the Latin alphabet in the string, * There is at least one of three listed symbols in the string: '#', '*', '&'. <image> Considering that these are programming classes it is not easy to write the password. For each character of the password we have a fixed string of length m, on each of these n strings there is a pointer on some character. The i-th character displayed on the screen is the pointed character in the i-th string. Initially, all pointers are on characters with indexes 1 in the corresponding strings (all positions are numbered starting from one). During one operation Dasha can move a pointer in one string one character to the left or to the right. Strings are cyclic, it means that when we move the pointer which is on the character with index 1 to the left, it moves to the character with the index m, and when we move it to the right from the position m it moves to the position 1. You need to determine the minimum number of operations necessary to make the string displayed on the screen a valid password. Input The first line contains two integers n, m (3 ≤ n ≤ 50, 1 ≤ m ≤ 50) — the length of the password and the length of strings which are assigned to password symbols. Each of the next n lines contains the string which is assigned to the i-th symbol of the password string. Its length is m, it consists of digits, lowercase English letters, and characters '#', '*' or '&'. You have such input data that you can always get a valid password. Output Print one integer — the minimum number of operations which is necessary to make the string, which is displayed on the screen, a valid password. Examples Input 3 4 1**2 a3*0 c4** Output 1 Input 5 5 #*&amp;#* *a1c&amp; &amp;q2w* #a3c# *&amp;#*&amp; Output 3 Note In the first test it is necessary to move the pointer of the third string to one left to get the optimal answer. <image> In the second test one of possible algorithms will be: * to move the pointer of the second symbol once to the right. * to move the pointer of the third symbol twice to the right. <image> Tags: brute force, dp, implementation Correct Solution: ``` read = lambda: map(int, input().split()) n, m = read() a = [input() for i in range(n)] c1 = '1234567890' c2 = 'qwertyuiopasdfghjklzxcvbnm' c3 = '#&*' inf = 10 ** 20 l1 = [inf] * n l2 = [inf] * n l3 = [inf] * n for i in range(n): for j in range(m): if a[i][j] in c1: l1[i] = min(l1[i], j, m - j) if a[i][j] in c2: l2[i] = min(l2[i], j, m - j) if a[i][j] in c3: l3[i] = min(l3[i], j, m - j) ans = inf for i in range(n): for j in range(n): for k in range(n): if len({i, j, k}) < 3: continue cur = l1[i] + l2[j] + l3[k] ans = min(ans, cur) print(ans) ```

Provide tags and a correct Python 3 solution for this coding contest problem. After overcoming the stairs Dasha came to classes. She needed to write a password to begin her classes. The password is a string of length n which satisfies the following requirements: * There is at least one digit in the string, * There is at least one lowercase (small) letter of the Latin alphabet in the string, * There is at least one of three listed symbols in the string: '#', '*', '&'. <image> Considering that these are programming classes it is not easy to write the password. For each character of the password we have a fixed string of length m, on each of these n strings there is a pointer on some character. The i-th character displayed on the screen is the pointed character in the i-th string. Initially, all pointers are on characters with indexes 1 in the corresponding strings (all positions are numbered starting from one). During one operation Dasha can move a pointer in one string one character to the left or to the right. Strings are cyclic, it means that when we move the pointer which is on the character with index 1 to the left, it moves to the character with the index m, and when we move it to the right from the position m it moves to the position 1. You need to determine the minimum number of operations necessary to make the string displayed on the screen a valid password. Input The first line contains two integers n, m (3 ≤ n ≤ 50, 1 ≤ m ≤ 50) — the length of the password and the length of strings which are assigned to password symbols. Each of the next n lines contains the string which is assigned to the i-th symbol of the password string. Its length is m, it consists of digits, lowercase English letters, and characters '#', '*' or '&'. You have such input data that you can always get a valid password. Output Print one integer — the minimum number of operations which is necessary to make the string, which is displayed on the screen, a valid password. Examples Input 3 4 1**2 a3*0 c4** Output 1 Input 5 5 #*&amp;#* *a1c&amp; &amp;q2w* #a3c# *&amp;#*&amp; Output 3 Note In the first test it is necessary to move the pointer of the third string to one left to get the optimal answer. <image> In the second test one of possible algorithms will be: * to move the pointer of the second symbol once to the right. * to move the pointer of the third symbol twice to the right. <image> Tags: brute force, dp, implementation Correct Solution: ``` n,m=map(int,input().split()) a=[] for i in range(65,91): a.append(chr(i+32)) b=[] f1=0 f2=0 f3=0 for i in range(0,10): b.append(str(i)) c=['*','#','&'] l=[] s=[] l1=[1000000000 for i in range(n)] l2=[1000000000 for i in range(n)] l3=[1000000000 for i in range(n)] f=[1 for i in range(n)] ff1=0 ff2=0 ff3=0 for i in range(n): l.append(list(str(input()))) s+=l[i][0] if s[i] in a: ff1+=1 elif s[i] in b: ff2+=1 else: ff3+=1 for i in range(n): if ff1==1: if l[i][0] in a: f[i]=0 elif ff2==1: if l[i][0] in b: f[i]=0 elif ff3==1: if l[i][0] in c: f[i]=0 for i in range(n): for j in range(m): if l[i][j] in a and f[i]: l1[i]=min(l1[i],j,m-j) for j in range(m): if l[i][j] in b and f[i]: l2[i]=min(l2[i],j,m-j) for j in range(m): if l[i][j] in c and f[i]: l3[i]=min(l3[i],j,m-j) for i in range(26): if chr(i+97) in s: f1=1 for i in range(10): if b[i] in s: f2=1 for i in range(3): if c[i] in s: f3=1 #print(l1,l2,l3) #print(f1,f2,f3) if f1+f2+f3==3: print(0) exit() elif f1+f2+f3==2: if f1==0: print(min(l1)) elif f2==0: print(min(l2)) else: print(min(l3)) else: if f1==1: ans=20*m for i in range(n): for j in range(n): if i!=j and l2[i]<=1000 and l3[j]<=1000: ans=min(ans,l2[i]+l3[j]) elif f2==1: ans=20*m for i in range(n): for j in range(n): if i!=j and l1[i]<=1000 and l3[j]<=1000: ans=min(ans,l1[i]+l3[j]) elif f3==1: ans=20*m for i in range(n): for j in range(n): if i!=j and l1[i]<=1000 and l2[j]<=1000: ans=min(ans,l1[i]+l2[j]) print(ans) ```

Provide tags and a correct Python 3 solution for this coding contest problem. During a normal walk in the forest, Katie has stumbled upon a mysterious code! However, the mysterious code had some characters unreadable. She has written down this code as a string c consisting of lowercase English characters and asterisks ("*"), where each of the asterisks denotes an unreadable character. Excited with her discovery, Katie has decided to recover the unreadable characters by replacing each asterisk with arbitrary lowercase English letter (different asterisks might be replaced with different letters). Katie has a favorite string s and a not-so-favorite string t and she would love to recover the mysterious code so that it has as many occurrences of s as possible and as little occurrences of t as possible. Formally, let's denote f(x, y) as the number of occurrences of y in x (for example, f(aababa, ab) = 2). Katie wants to recover the code c' conforming to the original c, such that f(c', s) - f(c', t) is largest possible. However, Katie is not very good at recovering codes in general, so she would like you to help her out. Input The first line contains string c (1 ≤ |c| ≤ 1000) — the mysterious code . It is guaranteed that c consists of lowercase English characters and asterisks "*" only. The second and third line contain strings s and t respectively (1 ≤ |s|, |t| ≤ 50, s ≠ t). It is guaranteed that s and t consist of lowercase English characters only. Output Print a single integer — the largest possible value of f(c', s) - f(c', t) of the recovered code. Examples Input ***** katie shiro Output 1 Input caat caat a Output -1 Input *a* bba b Output 0 Input *** cc z Output 2 Note In the first example, for c' equal to "katie" f(c', s) = 1 and f(c', t) = 0, which makes f(c', s) - f(c', t) = 1 which is the largest possible. In the second example, the only c' conforming to the given c is "caat". The corresponding f(c', s) - f(c', t) = 1 - 2 = -1. In the third example, there are multiple ways to recover the code such that f(c', s) - f(c', t) is largest possible, for example "aaa", "aac", or even "zaz". The value of f(c', s) - f(c', t) = 0 for all of these recovered codes. In the fourth example, the optimal recovered code c' would be "ccc". The corresponding f(c', s) - f(c', t) = 2.

To achieve that, he sneaked into the administrator's office and stole a piece of paper with a list of n passwords — strings, consists of small Latin letters. Hacker went home and started preparing to hack AtForces. He found that the system contains only passwords from the stolen list and that the system determines the equivalence of the passwords a and b as follows: * two passwords a and b are equivalent if there is a letter, that exists in both a and b; * two passwords a and b are equivalent if there is a password c from the list, which is equivalent to both a and b. If a password is set in the system and an equivalent one is applied to access the system, then the user is accessed into the system. For example, if the list contain passwords "a", "b", "ab", "d", then passwords "a", "b", "ab" are equivalent to each other, but the password "d" is not equivalent to any other password from list. In other words, if: * admin's password is "b", then you can access to system by using any of this passwords: "a", "b", "ab"; * admin's password is "d", then you can access to system by using only "d". Only one password from the list is the admin's password from the testing system. Help hacker to calculate the minimal number of passwords, required to guaranteed access to the system. Keep in mind that the hacker does not know which password is set in the system. Input The first line contain integer n (1 ≤ n ≤ 2 ⋅ 10^5) — number of passwords in the list. Next n lines contains passwords from the list – non-empty strings s_i, with length at most 50 letters. Some of the passwords may be equal. It is guaranteed that the total length of all passwords does not exceed 10^6 letters. All of them consist only of lowercase Latin letters. Output In a single line print the minimal number of passwords, the use of which will allow guaranteed to access the system. Examples Input 4 a b ab d Output 2 Input 3 ab bc abc Output 1 Input 1 codeforces Output 1 Note In the second example hacker need to use any of the passwords to access the system.

Provide tags and a correct Python 3 solution for this coding contest problem. One unknown hacker wants to get the admin's password of AtForces testing system, to get problems from the next contest. To achieve that, he sneaked into the administrator's office and stole a piece of paper with a list of n passwords — strings, consists of small Latin letters. Hacker went home and started preparing to hack AtForces. He found that the system contains only passwords from the stolen list and that the system determines the equivalence of the passwords a and b as follows: * two passwords a and b are equivalent if there is a letter, that exists in both a and b; * two passwords a and b are equivalent if there is a password c from the list, which is equivalent to both a and b. If a password is set in the system and an equivalent one is applied to access the system, then the user is accessed into the system. For example, if the list contain passwords "a", "b", "ab", "d", then passwords "a", "b", "ab" are equivalent to each other, but the password "d" is not equivalent to any other password from list. In other words, if: * admin's password is "b", then you can access to system by using any of this passwords: "a", "b", "ab"; * admin's password is "d", then you can access to system by using only "d". Only one password from the list is the admin's password from the testing system. Help hacker to calculate the minimal number of passwords, required to guaranteed access to the system. Keep in mind that the hacker does not know which password is set in the system. Input The first line contain integer n (1 ≤ n ≤ 2 ⋅ 10^5) — number of passwords in the list. Next n lines contains passwords from the list – non-empty strings s_i, with length at most 50 letters. Some of the passwords may be equal. It is guaranteed that the total length of all passwords does not exceed 10^6 letters. All of them consist only of lowercase Latin letters. Output In a single line print the minimal number of passwords, the use of which will allow guaranteed to access the system. Examples Input 4 a b ab d Output 2 Input 3 ab bc abc Output 1 Input 1 codeforces Output 1 Note In the second example hacker need to use any of the passwords to access the system. Tags: dfs and similar, dsu, graphs Correct Solution: ``` from sys import stdin input = stdin.readline if __name__ == '__main__': pdct = {} for _ in range(int(input())): s = input().strip() for c in s: if c not in pdct: pdct[c] = c l = list(filter(lambda o: pdct[o] != o, s)) if not l: p = s[0] else: p = l[0] while pdct[p] != p: p = pdct[p] for c in s: cc = c while pdct[cc] != cc: cc = pdct[cc] pdct[cc] = p cnt = 0 for k, v in pdct.items(): cnt += int(k == v) print(cnt) ```

Provide tags and a correct Python 3 solution for this coding contest problem. One unknown hacker wants to get the admin's password of AtForces testing system, to get problems from the next contest. To achieve that, he sneaked into the administrator's office and stole a piece of paper with a list of n passwords — strings, consists of small Latin letters. Hacker went home and started preparing to hack AtForces. He found that the system contains only passwords from the stolen list and that the system determines the equivalence of the passwords a and b as follows: * two passwords a and b are equivalent if there is a letter, that exists in both a and b; * two passwords a and b are equivalent if there is a password c from the list, which is equivalent to both a and b. If a password is set in the system and an equivalent one is applied to access the system, then the user is accessed into the system. For example, if the list contain passwords "a", "b", "ab", "d", then passwords "a", "b", "ab" are equivalent to each other, but the password "d" is not equivalent to any other password from list. In other words, if: * admin's password is "b", then you can access to system by using any of this passwords: "a", "b", "ab"; * admin's password is "d", then you can access to system by using only "d". Only one password from the list is the admin's password from the testing system. Help hacker to calculate the minimal number of passwords, required to guaranteed access to the system. Keep in mind that the hacker does not know which password is set in the system. Input The first line contain integer n (1 ≤ n ≤ 2 ⋅ 10^5) — number of passwords in the list. Next n lines contains passwords from the list – non-empty strings s_i, with length at most 50 letters. Some of the passwords may be equal. It is guaranteed that the total length of all passwords does not exceed 10^6 letters. All of them consist only of lowercase Latin letters. Output In a single line print the minimal number of passwords, the use of which will allow guaranteed to access the system. Examples Input 4 a b ab d Output 2 Input 3 ab bc abc Output 1 Input 1 codeforces Output 1 Note In the second example hacker need to use any of the passwords to access the system. Tags: dfs and similar, dsu, graphs Correct Solution: ``` def union(x, y): xr = find(x) yr = find(y) root[yr] = xr def find(x): if root[x] != x: x = find(root[x]) return x import sys input = sys.stdin.readline used = set() root = dict() for _ in range(int(input())): s = input().rstrip() for j in s: if ord(j) - 97 not in root: root[ord(j) - 97] = ord(j) - 97 union(ord(s[0]) - 97, ord(j) - 97) for i in root: used.add(find(root[i])) print(used.__len__()) ```

Provide tags and a correct Python 3 solution for this coding contest problem. One unknown hacker wants to get the admin's password of AtForces testing system, to get problems from the next contest. To achieve that, he sneaked into the administrator's office and stole a piece of paper with a list of n passwords — strings, consists of small Latin letters. Hacker went home and started preparing to hack AtForces. He found that the system contains only passwords from the stolen list and that the system determines the equivalence of the passwords a and b as follows: * two passwords a and b are equivalent if there is a letter, that exists in both a and b; * two passwords a and b are equivalent if there is a password c from the list, which is equivalent to both a and b. If a password is set in the system and an equivalent one is applied to access the system, then the user is accessed into the system. For example, if the list contain passwords "a", "b", "ab", "d", then passwords "a", "b", "ab" are equivalent to each other, but the password "d" is not equivalent to any other password from list. In other words, if: * admin's password is "b", then you can access to system by using any of this passwords: "a", "b", "ab"; * admin's password is "d", then you can access to system by using only "d". Only one password from the list is the admin's password from the testing system. Help hacker to calculate the minimal number of passwords, required to guaranteed access to the system. Keep in mind that the hacker does not know which password is set in the system. Input The first line contain integer n (1 ≤ n ≤ 2 ⋅ 10^5) — number of passwords in the list. Next n lines contains passwords from the list – non-empty strings s_i, with length at most 50 letters. Some of the passwords may be equal. It is guaranteed that the total length of all passwords does not exceed 10^6 letters. All of them consist only of lowercase Latin letters. Output In a single line print the minimal number of passwords, the use of which will allow guaranteed to access the system. Examples Input 4 a b ab d Output 2 Input 3 ab bc abc Output 1 Input 1 codeforces Output 1 Note In the second example hacker need to use any of the passwords to access the system. Tags: dfs and similar, dsu, graphs Correct Solution: ``` from collections import deque from sys import stdin, stdout read, whrite = stdin.readline, stdout.write g = [[] for i in range(300000)] visited = [False] * 300000 def dfs(i): pilha = deque() pilha.append(i) visited[i] = 1 while pilha: i = pilha.pop() for v in g[i]: if not visited[v]: visited[v] = True pilha.append(v) n = int(read()) for i in range(n): word = read().strip() for j in word: g[i].append(n + ord(j)) g[n + ord(j)].append(i) resp = 0 for i in range(n): if not visited[i]: dfs(i) resp += 1 print(resp) ```

Provide tags and a correct Python 3 solution for this coding contest problem. One unknown hacker wants to get the admin's password of AtForces testing system, to get problems from the next contest. To achieve that, he sneaked into the administrator's office and stole a piece of paper with a list of n passwords — strings, consists of small Latin letters. Hacker went home and started preparing to hack AtForces. He found that the system contains only passwords from the stolen list and that the system determines the equivalence of the passwords a and b as follows: * two passwords a and b are equivalent if there is a letter, that exists in both a and b; * two passwords a and b are equivalent if there is a password c from the list, which is equivalent to both a and b. If a password is set in the system and an equivalent one is applied to access the system, then the user is accessed into the system. For example, if the list contain passwords "a", "b", "ab", "d", then passwords "a", "b", "ab" are equivalent to each other, but the password "d" is not equivalent to any other password from list. In other words, if: * admin's password is "b", then you can access to system by using any of this passwords: "a", "b", "ab"; * admin's password is "d", then you can access to system by using only "d". Only one password from the list is the admin's password from the testing system. Help hacker to calculate the minimal number of passwords, required to guaranteed access to the system. Keep in mind that the hacker does not know which password is set in the system. Input The first line contain integer n (1 ≤ n ≤ 2 ⋅ 10^5) — number of passwords in the list. Next n lines contains passwords from the list – non-empty strings s_i, with length at most 50 letters. Some of the passwords may be equal. It is guaranteed that the total length of all passwords does not exceed 10^6 letters. All of them consist only of lowercase Latin letters. Output In a single line print the minimal number of passwords, the use of which will allow guaranteed to access the system. Examples Input 4 a b ab d Output 2 Input 3 ab bc abc Output 1 Input 1 codeforces Output 1 Note In the second example hacker need to use any of the passwords to access the system.

Provide tags and a correct Python 3 solution for this coding contest problem. One unknown hacker wants to get the admin's password of AtForces testing system, to get problems from the next contest. To achieve that, he sneaked into the administrator's office and stole a piece of paper with a list of n passwords — strings, consists of small Latin letters. Hacker went home and started preparing to hack AtForces. He found that the system contains only passwords from the stolen list and that the system determines the equivalence of the passwords a and b as follows: * two passwords a and b are equivalent if there is a letter, that exists in both a and b; * two passwords a and b are equivalent if there is a password c from the list, which is equivalent to both a and b. If a password is set in the system and an equivalent one is applied to access the system, then the user is accessed into the system. For example, if the list contain passwords "a", "b", "ab", "d", then passwords "a", "b", "ab" are equivalent to each other, but the password "d" is not equivalent to any other password from list. In other words, if: * admin's password is "b", then you can access to system by using any of this passwords: "a", "b", "ab"; * admin's password is "d", then you can access to system by using only "d". Only one password from the list is the admin's password from the testing system. Help hacker to calculate the minimal number of passwords, required to guaranteed access to the system. Keep in mind that the hacker does not know which password is set in the system. Input The first line contain integer n (1 ≤ n ≤ 2 ⋅ 10^5) — number of passwords in the list. Next n lines contains passwords from the list – non-empty strings s_i, with length at most 50 letters. Some of the passwords may be equal. It is guaranteed that the total length of all passwords does not exceed 10^6 letters. All of them consist only of lowercase Latin letters. Output In a single line print the minimal number of passwords, the use of which will allow guaranteed to access the system. Examples Input 4 a b ab d Output 2 Input 3 ab bc abc Output 1 Input 1 codeforces Output 1 Note In the second example hacker need to use any of the passwords to access the system.

Provide tags and a correct Python 3 solution for this coding contest problem. One unknown hacker wants to get the admin's password of AtForces testing system, to get problems from the next contest. To achieve that, he sneaked into the administrator's office and stole a piece of paper with a list of n passwords — strings, consists of small Latin letters. Hacker went home and started preparing to hack AtForces. He found that the system contains only passwords from the stolen list and that the system determines the equivalence of the passwords a and b as follows: * two passwords a and b are equivalent if there is a letter, that exists in both a and b; * two passwords a and b are equivalent if there is a password c from the list, which is equivalent to both a and b. If a password is set in the system and an equivalent one is applied to access the system, then the user is accessed into the system. For example, if the list contain passwords "a", "b", "ab", "d", then passwords "a", "b", "ab" are equivalent to each other, but the password "d" is not equivalent to any other password from list. In other words, if: * admin's password is "b", then you can access to system by using any of this passwords: "a", "b", "ab"; * admin's password is "d", then you can access to system by using only "d". Only one password from the list is the admin's password from the testing system. Help hacker to calculate the minimal number of passwords, required to guaranteed access to the system. Keep in mind that the hacker does not know which password is set in the system. Input The first line contain integer n (1 ≤ n ≤ 2 ⋅ 10^5) — number of passwords in the list. Next n lines contains passwords from the list – non-empty strings s_i, with length at most 50 letters. Some of the passwords may be equal. It is guaranteed that the total length of all passwords does not exceed 10^6 letters. All of them consist only of lowercase Latin letters. Output In a single line print the minimal number of passwords, the use of which will allow guaranteed to access the system. Examples Input 4 a b ab d Output 2 Input 3 ab bc abc Output 1 Input 1 codeforces Output 1 Note In the second example hacker need to use any of the passwords to access the system.

Provide tags and a correct Python 3 solution for this coding contest problem. One unknown hacker wants to get the admin's password of AtForces testing system, to get problems from the next contest. To achieve that, he sneaked into the administrator's office and stole a piece of paper with a list of n passwords — strings, consists of small Latin letters. Hacker went home and started preparing to hack AtForces. He found that the system contains only passwords from the stolen list and that the system determines the equivalence of the passwords a and b as follows: * two passwords a and b are equivalent if there is a letter, that exists in both a and b; * two passwords a and b are equivalent if there is a password c from the list, which is equivalent to both a and b. If a password is set in the system and an equivalent one is applied to access the system, then the user is accessed into the system. For example, if the list contain passwords "a", "b", "ab", "d", then passwords "a", "b", "ab" are equivalent to each other, but the password "d" is not equivalent to any other password from list. In other words, if: * admin's password is "b", then you can access to system by using any of this passwords: "a", "b", "ab"; * admin's password is "d", then you can access to system by using only "d". Only one password from the list is the admin's password from the testing system. Help hacker to calculate the minimal number of passwords, required to guaranteed access to the system. Keep in mind that the hacker does not know which password is set in the system. Input The first line contain integer n (1 ≤ n ≤ 2 ⋅ 10^5) — number of passwords in the list. Next n lines contains passwords from the list – non-empty strings s_i, with length at most 50 letters. Some of the passwords may be equal. It is guaranteed that the total length of all passwords does not exceed 10^6 letters. All of them consist only of lowercase Latin letters. Output In a single line print the minimal number of passwords, the use of which will allow guaranteed to access the system. Examples Input 4 a b ab d Output 2 Input 3 ab bc abc Output 1 Input 1 codeforces Output 1 Note In the second example hacker need to use any of the passwords to access the system. Tags: dfs and similar, dsu, graphs Correct Solution: ``` def union(x, y): xr = find(x) yr = find(y) root[xr] = yr def find(x): while root[x] != x: x = root[x] return x import sys input = sys.stdin.readline used = set() root = dict() for _ in range(int(input())): s = input().rstrip() for j in s: if ord(j) - 97 not in root: root[ord(j) - 97] = ord(j) - 97 union(ord(s[0]) - 97, ord(j) - 97) for i in root: used.add(find(root[i])) print(len(used)) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Returning back to problem solving, Gildong is now studying about palindromes. He learned that a palindrome is a string that is the same as its reverse. For example, strings "pop", "noon", "x", and "kkkkkk" are palindromes, while strings "moon", "tv", and "abab" are not. An empty string is also a palindrome. Gildong loves this concept so much, so he wants to play with it. He has n distinct strings of equal length m. He wants to discard some of the strings (possibly none or all) and reorder the remaining strings so that the concatenation becomes a palindrome. He also wants the palindrome to be as long as possible. Please help him find one. Input The first line contains two integers n and m (1 ≤ n ≤ 100, 1 ≤ m ≤ 50) — the number of strings and the length of each string. Next n lines contain a string of length m each, consisting of lowercase Latin letters only. All strings are distinct. Output In the first line, print the length of the longest palindrome string you made. In the second line, print that palindrome. If there are multiple answers, print any one of them. If the palindrome is empty, print an empty line or don't print this line at all. Examples Input 3 3 tab one bat Output 6 tabbat Input 4 2 oo ox xo xx Output 6 oxxxxo Input 3 5 hello codef orces Output 0 Input 9 4 abab baba abcd bcde cdef defg wxyz zyxw ijji Output 20 ababwxyzijjizyxwbaba Note In the first example, "battab" is also a valid answer. In the second example, there can be 4 different valid answers including the sample output. We are not going to provide any hints for what the others are. In the third example, the empty string is the only valid palindrome string.

Provide tags and a correct Python 3 solution for this coding contest problem. Returning back to problem solving, Gildong is now studying about palindromes. He learned that a palindrome is a string that is the same as its reverse. For example, strings "pop", "noon", "x", and "kkkkkk" are palindromes, while strings "moon", "tv", and "abab" are not. An empty string is also a palindrome. Gildong loves this concept so much, so he wants to play with it. He has n distinct strings of equal length m. He wants to discard some of the strings (possibly none or all) and reorder the remaining strings so that the concatenation becomes a palindrome. He also wants the palindrome to be as long as possible. Please help him find one. Input The first line contains two integers n and m (1 ≤ n ≤ 100, 1 ≤ m ≤ 50) — the number of strings and the length of each string. Next n lines contain a string of length m each, consisting of lowercase Latin letters only. All strings are distinct. Output In the first line, print the length of the longest palindrome string you made. In the second line, print that palindrome. If there are multiple answers, print any one of them. If the palindrome is empty, print an empty line or don't print this line at all. Examples Input 3 3 tab one bat Output 6 tabbat Input 4 2 oo ox xo xx Output 6 oxxxxo Input 3 5 hello codef orces Output 0 Input 9 4 abab baba abcd bcde cdef defg wxyz zyxw ijji Output 20 ababwxyzijjizyxwbaba Note In the first example, "battab" is also a valid answer. In the second example, there can be 4 different valid answers including the sample output. We are not going to provide any hints for what the others are. In the third example, the empty string is the only valid palindrome string. Tags: brute force, constructive algorithms, greedy, implementation, strings Correct Solution: ``` n, m = map(int, input().split()) a = [] for _ in range(n): s = input() a.append(s) def is_palindrome(s1, s2): eh = True for i in range(len(s1)): if s1[i] != s2[m-i-1]: eh = False break return eh def is_palindrome_alone(s1): eh = True for i in range(len(s1)): if s1[i] != s1[m-i-1]: eh = False break return eh together = [] for i in range(len(a)): for j in range(i+1, len(a)): if a[i] != -1 and a[j] != -1 and is_palindrome(a[i], a[j]): together.append([a[i], a[j]]) a[i] = -1 a[j] = -1 alone = [] for i, s in enumerate(a): if s != -1 and is_palindrome_alone(s): alone.append(s) a[i] = -1 break stack = [] ans = [] for i in together: ans.append(i[0]) stack.append(i[1]) for i in alone: ans.append(i) while len(stack): ans.append(stack.pop()) ans = "".join(ans) print(len(ans)) print(ans) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Returning back to problem solving, Gildong is now studying about palindromes. He learned that a palindrome is a string that is the same as its reverse. For example, strings "pop", "noon", "x", and "kkkkkk" are palindromes, while strings "moon", "tv", and "abab" are not. An empty string is also a palindrome. Gildong loves this concept so much, so he wants to play with it. He has n distinct strings of equal length m. He wants to discard some of the strings (possibly none or all) and reorder the remaining strings so that the concatenation becomes a palindrome. He also wants the palindrome to be as long as possible. Please help him find one. Input The first line contains two integers n and m (1 ≤ n ≤ 100, 1 ≤ m ≤ 50) — the number of strings and the length of each string. Next n lines contain a string of length m each, consisting of lowercase Latin letters only. All strings are distinct. Output In the first line, print the length of the longest palindrome string you made. In the second line, print that palindrome. If there are multiple answers, print any one of them. If the palindrome is empty, print an empty line or don't print this line at all. Examples Input 3 3 tab one bat Output 6 tabbat Input 4 2 oo ox xo xx Output 6 oxxxxo Input 3 5 hello codef orces Output 0 Input 9 4 abab baba abcd bcde cdef defg wxyz zyxw ijji Output 20 ababwxyzijjizyxwbaba Note In the first example, "battab" is also a valid answer. In the second example, there can be 4 different valid answers including the sample output. We are not going to provide any hints for what the others are. In the third example, the empty string is the only valid palindrome string.

Provide tags and a correct Python 3 solution for this coding contest problem. Returning back to problem solving, Gildong is now studying about palindromes. He learned that a palindrome is a string that is the same as its reverse. For example, strings "pop", "noon", "x", and "kkkkkk" are palindromes, while strings "moon", "tv", and "abab" are not. An empty string is also a palindrome. Gildong loves this concept so much, so he wants to play with it. He has n distinct strings of equal length m. He wants to discard some of the strings (possibly none or all) and reorder the remaining strings so that the concatenation becomes a palindrome. He also wants the palindrome to be as long as possible. Please help him find one. Input The first line contains two integers n and m (1 ≤ n ≤ 100, 1 ≤ m ≤ 50) — the number of strings and the length of each string. Next n lines contain a string of length m each, consisting of lowercase Latin letters only. All strings are distinct. Output In the first line, print the length of the longest palindrome string you made. In the second line, print that palindrome. If there are multiple answers, print any one of them. If the palindrome is empty, print an empty line or don't print this line at all. Examples Input 3 3 tab one bat Output 6 tabbat Input 4 2 oo ox xo xx Output 6 oxxxxo Input 3 5 hello codef orces Output 0 Input 9 4 abab baba abcd bcde cdef defg wxyz zyxw ijji Output 20 ababwxyzijjizyxwbaba Note In the first example, "battab" is also a valid answer. In the second example, there can be 4 different valid answers including the sample output. We are not going to provide any hints for what the others are. In the third example, the empty string is the only valid palindrome string. Tags: brute force, constructive algorithms, greedy, implementation, strings Correct Solution: ``` n,m=map(int,input().split()) s=[] z="" for i in range(n): s.append(input()) count=0 x="" for i in range(int(n)): j=i+1 if(s[i]==s[i][::-1]): z=s[i] continue while(j<n): if(s[i]==s[j][::-1]): count+=1 x=s[i]+x+s[j] break j+=1 x=x[:int(len(x)/2)]+z+x[int(len(x)/2):] print(len(x)) print(x) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Returning back to problem solving, Gildong is now studying about palindromes. He learned that a palindrome is a string that is the same as its reverse. For example, strings "pop", "noon", "x", and "kkkkkk" are palindromes, while strings "moon", "tv", and "abab" are not. An empty string is also a palindrome. Gildong loves this concept so much, so he wants to play with it. He has n distinct strings of equal length m. He wants to discard some of the strings (possibly none or all) and reorder the remaining strings so that the concatenation becomes a palindrome. He also wants the palindrome to be as long as possible. Please help him find one. Input The first line contains two integers n and m (1 ≤ n ≤ 100, 1 ≤ m ≤ 50) — the number of strings and the length of each string. Next n lines contain a string of length m each, consisting of lowercase Latin letters only. All strings are distinct. Output In the first line, print the length of the longest palindrome string you made. In the second line, print that palindrome. If there are multiple answers, print any one of them. If the palindrome is empty, print an empty line or don't print this line at all. Examples Input 3 3 tab one bat Output 6 tabbat Input 4 2 oo ox xo xx Output 6 oxxxxo Input 3 5 hello codef orces Output 0 Input 9 4 abab baba abcd bcde cdef defg wxyz zyxw ijji Output 20 ababwxyzijjizyxwbaba Note In the first example, "battab" is also a valid answer. In the second example, there can be 4 different valid answers including the sample output. We are not going to provide any hints for what the others are. In the third example, the empty string is the only valid palindrome string. Tags: brute force, constructive algorithms, greedy, implementation, strings Correct Solution: ``` n, m = map(int, input().split()) s1 = "" s2 = "" sc = "" dat = [] for _ in range(n): dat.append(input()) while 0 < len(dat): s = dat[0] del dat[0] if sc == "": if s == "".join(reversed(s)): sc = s continue for j in range(0, len(dat)): ss = "".join(reversed(dat[j])) if s == ss: s1 = s1 + s s2 = dat[j] + s2 del dat[j] break res = s1 + sc + s2 #print("---") #print(s1) #print(sc) #print(s2) #print("---") print(len(res)) print(res) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Returning back to problem solving, Gildong is now studying about palindromes. He learned that a palindrome is a string that is the same as its reverse. For example, strings "pop", "noon", "x", and "kkkkkk" are palindromes, while strings "moon", "tv", and "abab" are not. An empty string is also a palindrome. Gildong loves this concept so much, so he wants to play with it. He has n distinct strings of equal length m. He wants to discard some of the strings (possibly none or all) and reorder the remaining strings so that the concatenation becomes a palindrome. He also wants the palindrome to be as long as possible. Please help him find one. Input The first line contains two integers n and m (1 ≤ n ≤ 100, 1 ≤ m ≤ 50) — the number of strings and the length of each string. Next n lines contain a string of length m each, consisting of lowercase Latin letters only. All strings are distinct. Output In the first line, print the length of the longest palindrome string you made. In the second line, print that palindrome. If there are multiple answers, print any one of them. If the palindrome is empty, print an empty line or don't print this line at all. Examples Input 3 3 tab one bat Output 6 tabbat Input 4 2 oo ox xo xx Output 6 oxxxxo Input 3 5 hello codef orces Output 0 Input 9 4 abab baba abcd bcde cdef defg wxyz zyxw ijji Output 20 ababwxyzijjizyxwbaba Note In the first example, "battab" is also a valid answer. In the second example, there can be 4 different valid answers including the sample output. We are not going to provide any hints for what the others are. In the third example, the empty string is the only valid palindrome string. Tags: brute force, constructive algorithms, greedy, implementation, strings Correct Solution: ``` n, m = map(int, input().split()) d = {} f = [] a = [] used = [False] * n for i in range(n): s = input() if s[::-1] in d: used[i] = True used[d[s[::-1]]] = True f = [s] + f + [s[::-1]] del d[s[::-1]] else: d[s] = i a.append(s) if len(f) % 2: print(len(f) * m) print(''.join(f)) else: for i in range(n): if not used[i] and a[i] == a[i][::-1]: f = f[:len(f) // 2] + [a[i]] + f[len(f) // 2:] break print(len(f) * m) print(''.join(f)) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Returning back to problem solving, Gildong is now studying about palindromes. He learned that a palindrome is a string that is the same as its reverse. For example, strings "pop", "noon", "x", and "kkkkkk" are palindromes, while strings "moon", "tv", and "abab" are not. An empty string is also a palindrome. Gildong loves this concept so much, so he wants to play with it. He has n distinct strings of equal length m. He wants to discard some of the strings (possibly none or all) and reorder the remaining strings so that the concatenation becomes a palindrome. He also wants the palindrome to be as long as possible. Please help him find one. Input The first line contains two integers n and m (1 ≤ n ≤ 100, 1 ≤ m ≤ 50) — the number of strings and the length of each string. Next n lines contain a string of length m each, consisting of lowercase Latin letters only. All strings are distinct. Output In the first line, print the length of the longest palindrome string you made. In the second line, print that palindrome. If there are multiple answers, print any one of them. If the palindrome is empty, print an empty line or don't print this line at all. Examples Input 3 3 tab one bat Output 6 tabbat Input 4 2 oo ox xo xx Output 6 oxxxxo Input 3 5 hello codef orces Output 0 Input 9 4 abab baba abcd bcde cdef defg wxyz zyxw ijji Output 20 ababwxyzijjizyxwbaba Note In the first example, "battab" is also a valid answer. In the second example, there can be 4 different valid answers including the sample output. We are not going to provide any hints for what the others are. In the third example, the empty string is the only valid palindrome string. Tags: brute force, constructive algorithms, greedy, implementation, strings Correct Solution: ``` n,m = map(int,input().split()) dic = {} dic2 = {} for i in range(n): s = input() temp = list(s) temp.reverse() rev = "".join(temp) if s == rev: if s not in dic2: dic2[s] = 0 dic2[s] += 1 elif s < rev: if s not in dic: dic[s] = [0,0] dic[s][0] += 1 else: if rev not in dic: dic[rev] = [0,0] dic[rev][1] += 1 lis = [] bis = [] for s in dic: temp = list(s) temp.reverse() rev = "".join(temp) for i in range(min(dic[s])): lis.append(s) bis.append(rev) sub = "" for s in dic2: if dic2[s] % 2 == 1: sub = s for i in range(dic2[s] // 2): lis.append(s) bis.append(s) bis.reverse() ans = "".join(lis) +sub+ "".join(bis) print (len(ans)) print (ans) ```

Provide tags and a correct Python 3 solution for this coding contest problem. Genos recently installed the game Zuma on his phone. In Zuma there exists a line of n gemstones, the i-th of which has color ci. The goal of the game is to destroy all the gemstones in the line as quickly as possible. In one second, Genos is able to choose exactly one continuous substring of colored gemstones that is a palindrome and remove it from the line. After the substring is removed, the remaining gemstones shift to form a solid line again. What is the minimum number of seconds needed to destroy the entire line? Let us remind, that the string (or substring) is called palindrome, if it reads same backwards or forward. In our case this means the color of the first gemstone is equal to the color of the last one, the color of the second gemstone is equal to the color of the next to last and so on. Input The first line of input contains a single integer n (1 ≤ n ≤ 500) — the number of gemstones. The second line contains n space-separated integers, the i-th of which is ci (1 ≤ ci ≤ n) — the color of the i-th gemstone in a line. Output Print a single integer — the minimum number of seconds needed to destroy the entire line. Examples Input 3 1 2 1 Output 1 Input 3 1 2 3 Output 3 Input 7 1 4 4 2 3 2 1 Output 2 Note In the first sample, Genos can destroy the entire line in one second. In the second sample, Genos can only destroy one gemstone at a time, so destroying three gemstones takes three seconds. In the third sample, to achieve the optimal time of two seconds, destroy palindrome 4 4 first and then destroy palindrome 1 2 3 2 1.

Provide tags and a correct Python 3 solution for this coding contest problem. The preferred way to generate user login in Polygon is to concatenate a prefix of the user's first name and a prefix of their last name, in that order. Each prefix must be non-empty, and any of the prefixes can be the full name. Typically there are multiple possible logins for each person. You are given the first and the last name of a user. Return the alphabetically earliest login they can get (regardless of other potential Polygon users). As a reminder, a prefix of a string s is its substring which occurs at the beginning of s: "a", "ab", "abc" etc. are prefixes of string "{abcdef}" but "b" and 'bc" are not. A string a is alphabetically earlier than a string b, if a is a prefix of b, or a and b coincide up to some position, and then a has a letter that is alphabetically earlier than the corresponding letter in b: "a" and "ab" are alphabetically earlier than "ac" but "b" and "ba" are alphabetically later than "ac". Input The input consists of a single line containing two space-separated strings: the first and the last names. Each character of each string is a lowercase English letter. The length of each string is between 1 and 10, inclusive. Output Output a single string — alphabetically earliest possible login formed from these names. The output should be given in lowercase as well. Examples Input harry potter Output hap Input tom riddle Output tomr Tags: brute force, greedy, sortings Correct Solution: ``` a=input().split() n=[] X='' for i in a[0]: X+=i n.append(X+a[1][0]) n=sorted(n) print(n[0]) ```

Provide tags and a correct Python 3 solution for this coding contest problem. The preferred way to generate user login in Polygon is to concatenate a prefix of the user's first name and a prefix of their last name, in that order. Each prefix must be non-empty, and any of the prefixes can be the full name. Typically there are multiple possible logins for each person. You are given the first and the last name of a user. Return the alphabetically earliest login they can get (regardless of other potential Polygon users). As a reminder, a prefix of a string s is its substring which occurs at the beginning of s: "a", "ab", "abc" etc. are prefixes of string "{abcdef}" but "b" and 'bc" are not. A string a is alphabetically earlier than a string b, if a is a prefix of b, or a and b coincide up to some position, and then a has a letter that is alphabetically earlier than the corresponding letter in b: "a" and "ab" are alphabetically earlier than "ac" but "b" and "ba" are alphabetically later than "ac". Input The input consists of a single line containing two space-separated strings: the first and the last names. Each character of each string is a lowercase English letter. The length of each string is between 1 and 10, inclusive. Output Output a single string — alphabetically earliest possible login formed from these names. The output should be given in lowercase as well. Examples Input harry potter Output hap Input tom riddle Output tomr Tags: brute force, greedy, sortings Correct Solution: ``` f,l=map(str,input().split()) i=1 j=0 while i<len(f): if ord(f[i])<ord(l[j]): i+=1 else: break print(f[0:i]+l[0]) ```

Provide tags and a correct Python 3 solution for this coding contest problem. The preferred way to generate user login in Polygon is to concatenate a prefix of the user's first name and a prefix of their last name, in that order. Each prefix must be non-empty, and any of the prefixes can be the full name. Typically there are multiple possible logins for each person. You are given the first and the last name of a user. Return the alphabetically earliest login they can get (regardless of other potential Polygon users). As a reminder, a prefix of a string s is its substring which occurs at the beginning of s: "a", "ab", "abc" etc. are prefixes of string "{abcdef}" but "b" and 'bc" are not. A string a is alphabetically earlier than a string b, if a is a prefix of b, or a and b coincide up to some position, and then a has a letter that is alphabetically earlier than the corresponding letter in b: "a" and "ab" are alphabetically earlier than "ac" but "b" and "ba" are alphabetically later than "ac". Input The input consists of a single line containing two space-separated strings: the first and the last names. Each character of each string is a lowercase English letter. The length of each string is between 1 and 10, inclusive. Output Output a single string — alphabetically earliest possible login formed from these names. The output should be given in lowercase as well. Examples Input harry potter Output hap Input tom riddle Output tomr Tags: brute force, greedy, sortings Correct Solution: ``` fname,lname = input().split() ans="" ans+=fname[0] for x in range(1,len(fname)): if ord(fname[x]) < ord(lname[0]): ans+=fname[x] else:break; ans+=lname[0] print(ans) ```

Provide tags and a correct Python 3 solution for this coding contest problem. The preferred way to generate user login in Polygon is to concatenate a prefix of the user's first name and a prefix of their last name, in that order. Each prefix must be non-empty, and any of the prefixes can be the full name. Typically there are multiple possible logins for each person. You are given the first and the last name of a user. Return the alphabetically earliest login they can get (regardless of other potential Polygon users). As a reminder, a prefix of a string s is its substring which occurs at the beginning of s: "a", "ab", "abc" etc. are prefixes of string "{abcdef}" but "b" and 'bc" are not. A string a is alphabetically earlier than a string b, if a is a prefix of b, or a and b coincide up to some position, and then a has a letter that is alphabetically earlier than the corresponding letter in b: "a" and "ab" are alphabetically earlier than "ac" but "b" and "ba" are alphabetically later than "ac". Input The input consists of a single line containing two space-separated strings: the first and the last names. Each character of each string is a lowercase English letter. The length of each string is between 1 and 10, inclusive. Output Output a single string — alphabetically earliest possible login formed from these names. The output should be given in lowercase as well. Examples Input harry potter Output hap Input tom riddle Output tomr Tags: brute force, greedy, sortings Correct Solution: ``` s = input().split(' ') result = s[0][0] end = s[1][0] for i in range(1, len(s[0])): if ord(s[0][i]) < ord(end): result += s[0][i] else: break result += end print(result) ```

Provide tags and a correct Python 3 solution for this coding contest problem. The preferred way to generate user login in Polygon is to concatenate a prefix of the user's first name and a prefix of their last name, in that order. Each prefix must be non-empty, and any of the prefixes can be the full name. Typically there are multiple possible logins for each person. You are given the first and the last name of a user. Return the alphabetically earliest login they can get (regardless of other potential Polygon users). As a reminder, a prefix of a string s is its substring which occurs at the beginning of s: "a", "ab", "abc" etc. are prefixes of string "{abcdef}" but "b" and 'bc" are not. A string a is alphabetically earlier than a string b, if a is a prefix of b, or a and b coincide up to some position, and then a has a letter that is alphabetically earlier than the corresponding letter in b: "a" and "ab" are alphabetically earlier than "ac" but "b" and "ba" are alphabetically later than "ac". Input The input consists of a single line containing two space-separated strings: the first and the last names. Each character of each string is a lowercase English letter. The length of each string is between 1 and 10, inclusive. Output Output a single string — alphabetically earliest possible login formed from these names. The output should be given in lowercase as well. Examples Input harry potter Output hap Input tom riddle Output tomr Tags: brute force, greedy, sortings Correct Solution: ``` inu=input().split() first,last=inu[0],inu[1] l,name,st=[],"","" for fi in first: st=st+fi name=st for se in last: name=name+se l.append(name) l.sort() print(l[0]) ```

Provide tags and a correct Python 3 solution for this coding contest problem. The preferred way to generate user login in Polygon is to concatenate a prefix of the user's first name and a prefix of their last name, in that order. Each prefix must be non-empty, and any of the prefixes can be the full name. Typically there are multiple possible logins for each person. You are given the first and the last name of a user. Return the alphabetically earliest login they can get (regardless of other potential Polygon users). As a reminder, a prefix of a string s is its substring which occurs at the beginning of s: "a", "ab", "abc" etc. are prefixes of string "{abcdef}" but "b" and 'bc" are not. A string a is alphabetically earlier than a string b, if a is a prefix of b, or a and b coincide up to some position, and then a has a letter that is alphabetically earlier than the corresponding letter in b: "a" and "ab" are alphabetically earlier than "ac" but "b" and "ba" are alphabetically later than "ac". Input The input consists of a single line containing two space-separated strings: the first and the last names. Each character of each string is a lowercase English letter. The length of each string is between 1 and 10, inclusive. Output Output a single string — alphabetically earliest possible login formed from these names. The output should be given in lowercase as well. Examples Input harry potter Output hap Input tom riddle Output tomr Tags: brute force, greedy, sortings Correct Solution: ``` first, last = input().split() if len(first) == 1: print(first[0]+last[0]) else: i=1 while i < len(first) and first[i] < last[0]: i+=1 print(first[:i]+last[0]) ```

Provide tags and a correct Python 3 solution for this coding contest problem. The preferred way to generate user login in Polygon is to concatenate a prefix of the user's first name and a prefix of their last name, in that order. Each prefix must be non-empty, and any of the prefixes can be the full name. Typically there are multiple possible logins for each person. You are given the first and the last name of a user. Return the alphabetically earliest login they can get (regardless of other potential Polygon users). As a reminder, a prefix of a string s is its substring which occurs at the beginning of s: "a", "ab", "abc" etc. are prefixes of string "{abcdef}" but "b" and 'bc" are not. A string a is alphabetically earlier than a string b, if a is a prefix of b, or a and b coincide up to some position, and then a has a letter that is alphabetically earlier than the corresponding letter in b: "a" and "ab" are alphabetically earlier than "ac" but "b" and "ba" are alphabetically later than "ac". Input The input consists of a single line containing two space-separated strings: the first and the last names. Each character of each string is a lowercase English letter. The length of each string is between 1 and 10, inclusive. Output Output a single string — alphabetically earliest possible login formed from these names. The output should be given in lowercase as well.

Provide tags and a correct Python 3 solution for this coding contest problem. The preferred way to generate user login in Polygon is to concatenate a prefix of the user's first name and a prefix of their last name, in that order. Each prefix must be non-empty, and any of the prefixes can be the full name. Typically there are multiple possible logins for each person. You are given the first and the last name of a user. Return the alphabetically earliest login they can get (regardless of other potential Polygon users). As a reminder, a prefix of a string s is its substring which occurs at the beginning of s: "a", "ab", "abc" etc. are prefixes of string "{abcdef}" but "b" and 'bc" are not. A string a is alphabetically earlier than a string b, if a is a prefix of b, or a and b coincide up to some position, and then a has a letter that is alphabetically earlier than the corresponding letter in b: "a" and "ab" are alphabetically earlier than "ac" but "b" and "ba" are alphabetically later than "ac". Input The input consists of a single line containing two space-separated strings: the first and the last names. Each character of each string is a lowercase English letter. The length of each string is between 1 and 10, inclusive. Output Output a single string — alphabetically earliest possible login formed from these names. The output should be given in lowercase as well. Examples Input harry potter Output hap Input tom riddle Output tomr Tags: brute force, greedy, sortings Correct Solution: ``` s = input() n, f = s.split(' ') s=n[0] i=1 while i < len(n) and n[i] < f[0]: s += n[i] i+=1 print(s+f[0]) ```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. The preferred way to generate user login in Polygon is to concatenate a prefix of the user's first name and a prefix of their last name, in that order. Each prefix must be non-empty, and any of the prefixes can be the full name. Typically there are multiple possible logins for each person. You are given the first and the last name of a user. Return the alphabetically earliest login they can get (regardless of other potential Polygon users). As a reminder, a prefix of a string s is its substring which occurs at the beginning of s: "a", "ab", "abc" etc. are prefixes of string "{abcdef}" but "b" and 'bc" are not. A string a is alphabetically earlier than a string b, if a is a prefix of b, or a and b coincide up to some position, and then a has a letter that is alphabetically earlier than the corresponding letter in b: "a" and "ab" are alphabetically earlier than "ac" but "b" and "ba" are alphabetically later than "ac". Input The input consists of a single line containing two space-separated strings: the first and the last names. Each character of each string is a lowercase English letter. The length of each string is between 1 and 10, inclusive. Output Output a single string — alphabetically earliest possible login formed from these names. The output should be given in lowercase as well.
