题目大意:输入一个字符串.输出它的下一个字典序排列. 字典序算法思想: 1.从右向左寻找字符串找出第一个a[i]<a[i+1]的位置i; 2.从右向左找出第一个大于a[i]的元素a[j]; 3.swap(a[i],a[j]) 4.将a[i+1]......到a[stelen(a)]倒序 5.输出a 代码例如以下: #include<iostream> #include<cstdio> #include <cstring> #include<algorithm…

题目: 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 repla…
