用strstr匹配字串的题，以下是代码。

#include <iostream>
#include <algorithm>
#include<string.h>
#include<math.h>
#include<stdio.h>
#include<string>using namespace std;
const int maxn = 1000000+10;
char  s1[maxn],s2[maxn];
int solve()
{int len1=strlen(s1),len2=strlen(s2);if(len1!=len2)return 0;for(int i=0; i<len1; i++){s1[i+len1]=s1[i];}s1[2*len1]='';
//    puts(s1);
//    puts(s2);if(strstr(s1,s2)==NULL)return 0;return 1;
}
int main()
{while(~scanf("%s %s",s1,s2)){if(solve()==1)printf("Yesn");elseprintf("Non");}return 0;
}
