The idea is to swap each of the remaining characters in the string.. Note: 0 is considered to be an even index. If two permutations look the same, only print one of them. Non-divisible subset Hackerrank solutions in c somesh. If one string is an exact prefix of the other it is lexicographically smaller, e.g., . For example, strings and .Our number of moves, .To convert to , we first delete all of the characters in moves. For eg, string ABC has 6 permutations. For example, s = [ab, ab, bc]. Will update it ASAP. Given an array of strings sorted in lexicographical order, print all of its permutations in strict lexicographical order. That means they are ordered by comparing their leftmost different characters. Strings are usually ordered in lexicographical order. Original Problem.
