实现获取下一个排列函数,这个算法需要将数字重新排列成字典序中数字更大的排列.如果不存在更大的排列,则重新将数字排列成最小的排列(即升序排列).修改必须是原地的,不开辟额外的内存空间.这是一些例子,输入位于左侧列,其相应输出位于右侧列.1,2,3 → 1,3,23,2,1 → 1,2,31,1,5 → 1,5,1详见:https://leetcode.com/problems/next-permutation/description/ Java实现: class Solution { public…

题目 下一个排列 给定一个整数数组来表示排列,找出其之后的一个排列. 样例 给出排列[1,3,2,3],其下一个排列是[1,3,3,2] 给出排列[4,3,2,1],其下一个排列是[1,2,3,4] 注意 排列中可能包含重复的整数 解题 和上一题求上一个排列应该很类似 1.对这个数,先从右到左找到递增序列的前一个位置,peakInd 2.若peakInd = -1 这个数直接逆序就是答案了 3.peakInd>= 0 peakInd这个位置的所,和 peakInd 到nums.size() -1…

题目描述: 中文: 实现获取下一个排列的函数,算法需要将给定数字序列重新排列成字典序中下一个更大的排列. 如果不存在下一个更大的排列,则将数字重新排列成最小的排列(即升序排列). 必须原地修改,只允许使用额外常数空间 英文: Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. If such arrangement…
题目: 给定一个整数,存放在数组中,求出该整数的下一个排列(字典顺序):要求原地置换,且不能分配额外的内存 举例: 1,2,3 → 1,3,2:  3,2,1 → 1,2,3:  1,1,5 → 1,5,1:   解题思路: 1. 由于要找出整数的下一个排列,且按照字典顺序,因此要找出当前排列中需要交换的的那个位,即找到从右到左第一个不满足升序的元素的前一个元素nums[index1], 以及从右到左第一个大于nums[index1]的元素nums[index2]; 2. 交换两个元素:因为是按…
