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). The replaceme…

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…

今天围观刘汝佳神犇的白书发现了一个好用的函数: next_permutation(); 可以用于可重, 或者不可重集, 寻找下一个排列. 时间复杂度尚不明. //适用于不可重和可重集的排列. # include <iostream> # include <algorithm> using namespace std; int a[1003], n; int main() { cin >> n; for (int i = 0; i < n; ++i ) cin &g…

http://www.lintcode.com/zh-cn/problem/next-permutation-ii/# 原题 给定一个若干整数的排列,给出按正数大小进行字典序从小到大排序后的下一个排列. 如果没有下一个排列,则输出字典序最小的序列. 样例 左边是原始排列,右边是对应的下一个排列. 1,2,3 → 1,3,2 3,2,1 → 1,2,3 1,1,5 → 1,5,1 解题思路(示例:[1,3,5,4,2]) 从后开始往前遍历,找到后一个元素大于前一个元素的时候记录前一个元素的指针(也…
