( 6254 ) C Marina and Vasya PROGRAMMING constructive algorithms greedy strings 1700

B"Marina loves strings of the same length and Vasya loves when there is a third string, different from them in exactly t characters. Help Vasya find at least one such string. More formally, you are given two strings s1, s2 of length n and number t. Let's denote as f(a, xe2 x80 x89b) the number of characters in which strings a and b are different. Then your task will be to find any string s3 of length n, such that f(s1, xe2 x80 x89s3) xe2 x80 x89= xe2 x80 x89f(s2, xe2 x80 x89s3) xe2 x80 x89= xe2 x80 x89t. If there is no such string, print xe2 x80 x89- xe2 x80 x891. The first line contains two integers n and t (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89105, 0 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89t xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n). The second line contains string s1 of length n, consisting of lowercase English letters. The third line contain string s2 of length n, consisting of lowercase English letters. Print a string of length n, differing from string s1 and from s2 in exactly t characters. Your string should consist only from lowercase English letters. If such string doesn't exist, print -1."...
