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.

import java.util.Scanner;

public class Main {

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