( 19889 ) B Codeforces Subsequences PROGRAMMING brute force constructive algorithms greedy math strings

B'Karl likes Codeforces and subsequences. He wants to find a string of lowercase English letters that contains at least k subsequences codeforces. Out of all possible strings, Karl wants to find a shortest one. Formally, a codeforces subsequence of a string s is a subset of ten characters of s that read codeforces from left to right. For example, codeforces contains codeforces a single time, while codeforcesisawesome contains codeforces four times: codeforcesisawesome, codeforcesisawesome, codeforcesisawesome, codeforcesisawesome. Help Karl find any shortest string that contains at least k codeforces subsequences. The only line contains a single integer k ( 1 <= q k <= q 10^{16}) . Print a shortest string of lowercase English letters that contains at least k codeforces subsequences. If there are several such strings, print any of them. '...
