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.

import java.util.Scanner;

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