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

In the first operation, kyoto becomes okyot.

In the second operation, okyot becomes tokyo.

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

'use strict'

function main(input) {

  const t = input.split('\n')[1];
  const s = input.split('\n')[0];

  let str = s;
  let ans  = false;

  for (let i = 0; i < s.length; i++) {
    if (str === t) {
      ans = true;
      break;
    } else {
      str = str.slice(1) + str.slice(0, 1);
    }
  }

  console.log(ans ? 'Yes' : 'No');
}

main(require("fs").readFileSync("/dev/stdin", "utf8"));
