next_permutation

实验了一下next_permutation

代码如下

 #include <cstdio>
 #include <cstdlib>
 #include <cstring>
 #include <iostream>
 #include <algorithm>
 using namespace std;

 int main(int argc, char const *argv[])
 {
     char s[] = "";
     int len = strlen(s);
     do {
         puts(s);
     }
     while(next_permutation(s,s+len));

     getchar();
     return ;
 }

效果如下
