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.

		String s = sc.next();
		String t = sc.next();
		boolean flag = false;
		for(int n=0;n<s.length();n++){
			String st = "";
			for(int m=0;m<s.length();m++){
				st += s.charAt((m+n)%s.length());
			}
			if(st.equals(t)){
				flag = true;
				break;
