这道题就是找规律,可以看出来下一个permutation的规律是:从右往左扫,找到第一个满足:nums[i-1] < nums[i]条件的,再找到从右到左第一个比nums[i-1]大的数,把它们swap,再把所有i-1之后的数字swap即可。边界条件:1. i = nums.length - 1,这时候i-1之后只有一个值, 2. 数组一直递减,这时候i变成0...

While the next permutation of arr = [3,2,1] is [1,2,3] because [3,2,1] does not have a lexicographical larger rearrangement. Given an array of integers nums, find the next permutation of nums. The replacement must be in place and use only constant extra memory. ...
Some of the example in the examples repository are based on the experiments from published papers that have either used the library directly, or which led to some of the code in the library. Java Modules This library provides a Java module, org.cicirello.jpt. To use in your project, add...
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 ...
