Algorithem_PermutationInString Given two strings s1 and s2, return true if s2 contains a permutation of s1, or false otherwise. In other words, return true if one of s1's permutations is the substring of s2. <!--more--> Example 1: 代码语言:Swift AI代码解释 Input:s1="ab",s2="eidba...
Input:s1= "ab" s2 = "eidboaoo"Output: False https://leetcode.com/problems/permutation-in-string/discuss/102588/Java-Solution-Sliding-Window1. Howdowe know string p is a permutation of string s? Easy, each character in p is in s too. So we canabstractall permutation strings of s to ...

s=String.copyValueOf(char_s); returns; } } 运行结果: method2: AABB ABAB ABBA BAAB BABA BBAA 原Reference里的那个哥们儿的代码有点问题,他的代码用java实现后只能完成类似于ABCD,AABC等string的无重复全排列,而无法做到AABB这种类型的无重复全排列。
