这是链接 好久木有用过c/cpp的缘故，好多细节都忘了。导致踩了好几个坑。最坑的还是要两个换行符了，一开始没注意，wa了n次还摸不着头脑。

#include 
#include "stdio.h"
#include "string.h"
int main() {
    int N = 0;
    char s[82];
    scanf("%d",&N);
    while (N--){
        scanf("%s",s);
        int n = strlen(s);
        for (int i = 0; i < n; ++i) {
            if (n% (i + 1) == 0){
                bool flag = true;
                for (int j = (i + 1); j < n; ++j) {
                    if (s[j % (i + 1)] != s[j]){
                        flag = false;
                        break;
                    }
                }
                if (flag == true){
                    printf("%d\n",i + 1);
                    if (N != 0){ printf("\n");}
                    break;
                }
            }
        }
    }
    return 0;
