题目大意：给出一个字符串，输出一比这字符串大的最小的下一字符串

解题思路：next_permutation函数的调用

#include <iostream>#include <string.h>#include <iostream>#include <algorithm>using namespace std;char str[1000];int main() {    while(scanf("%s", str) && str[0] != '#') {        if(next_permutation(str, str+strlen(str)))            printf("%s\n", str);        else            printf("No Successor\n");    }    return 0;}
