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

abc

Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

function Main(input) {
    var inputArr = input.split('\n');
    var S = inputArr[0];
    var T = inputArr[1];
    var flg = false;

    for(var i = 0 ; i <= S.length ; ++i) {
        if (S === T) {
            flg = true;
            break;
        }
        S = S.slice(S.length - 1) + S.slice(0, S.length-1);
    }

    if (flg) console.log('Yes');
    else console.log('No');
}
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
