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...

Leetcode 46. Permutation 全排列 解决思路: 排列:从n个元素中任取m个元素,并按照一定的顺序进行排列,称为排列; 全排列:当n==m时,称为全排列; 比如:集合{ 1,2,3}的全排列为: { 1 2 3} { 1 3 2 } { 2 1 3 } { 2 3 1 } { 3 2 1 } { 3 1 2 } 我们可以将这个排列问题画成图形...
[Leetcode] Next Permutation 下一个排列 Next Permutation Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. If such arrangement is not possible, it must rearrange it as the lowest possible order (ie, sorted in ascending order)....
