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

Yes

In the first operation, kyoto becomes okyot.

In the second operation, okyot becomes tokyo.

Sample Input 2

import java.util.*;
public class Main {

	public static void main(String[] args) {
		Scanner stdIn = new Scanner(System.in);
		String s = stdIn.next();
		String t = stdIn.next();
		
		boolean ans = false;
		
		
		for(int i = 0; i < s.length(); i++) {
			if(s.equals(t)) {
				ans = true;
				break;
			}
			s = s.substring(s.length()-1)+s.substring(0,s.length()-1);
		}
		if(ans) {
			System.out.println("Yes");
		}else {
			System.out.println("No");
		}
		
	}
