To try to get a list of all the permutations of Integers. If such arrangement is not possible, it must rearrange it as the lowest possible order (ie, sorted in ascending order). Given a word, find lexicographically smaller permutation of it. Next Permutation. In other words, one of the first string’s permutations is the substring of the second string. This is my solution in java. The idea behind this approach is that one string will be a permutation of another string only if both of them contain the same characters the same number of times. Each character should appear exactly times of 2, e.g. 解题方法. Example 1: Input: s = "aacaba" Output: 2 Explanation: There are 5 ways to split "aacaba" and 2 of them are good.
