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…
The set [1,2,3,-,n] contains a total of n! unique permutations. By listing and labeling all of the permutations in order, We get the following sequence (ie, for n = 3): 1 "123" 2 "132" 3 "213" 4 "231" 5 "312&qu…
给出集合 [1,2,3,-,n],其所有元素共有 n! 种排列. 按大小顺序列出所有排列情况,并一一标记,当 n = 3 时, 所有排列如下: "123" "132" "213" "231" "312" "321" 给定 n 和 k,返回第 k 个排列. 说明: 给定 n 的范围是 [1, 9]. 给定 k 的范围是[1,  n!]. 示例 1: 输入: n = 3, k = 3 输出:…
