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...
Given two strings s1 and s2, write a function to return true if s2 contains the permutation of s1. In other words, one of the first string's permutations is the substring of the second string. Example 1: Input:s1 = "ab" s2 = "eidbaooo" Output:True Explanation: s2 contains one per...

之前曾在Java for LeetCode 046 Permutations和Java for LeetCode 031 Next Permutation做过关于字典排序的算法,但是可以肯定,这种近乎暴力枚举的算法肯定是通不过测试的!通过观察发现k / factorial(n - 1)其实就代表了str的第一个字母,顺着这个思路以此类推即可,JAVA实现如下: static public String getPermutation(in...
