Problem Statement

You are given string S and T consisting of lowercase English letters.

Determine if S equals T after rotation.

That is, determine if S equals T after the following operation is performed some number of times:

Operation: Let S = S_1 S_2 ... S_{|S|}. Change S to S_{|S|} S_1 S_2 ... S_{|S|-1}.

Here, |X| denotes the length of the string X.

Constraints

2 \leq |S| \leq 100

|S| = |T|

S and T consist of lowercase English letters.

Input

Input is given from Standard Input in the following format:

S
T

Output

If S equals T after rotation, print Yes; if it does not, print No.

Sample Input 1

kyoto
tokyo

Sample Output 1

In the first operation, kyoto becomes okyot.

In the second operation, okyot becomes tokyo.

#include<bits/stdc++.h>
using namespace std;

string chng(string t){
  string work = t;
  int n = t.size();
  work.at(0) = t.at(n-1);
  for(int i = 1;i < n;i++){
      work.at(i) = t.at(i-1);
  }
  return work;
}

int main(){
  string s,t,r,ans;
  cin >> s >> t;
  r = s; ans = "No";
  for(int i = 0;i < s.size();i++){
    if(r == t){
      ans = "Yes";
      break;
    }else{
      r = chng(r);
    }
  }
  cout << ans << endl;

  return 0;
