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.

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

'use strict'
const main = input => {
  const line = input.split('\n')
  const T = line[1]
  let ar = line[0].split('')
  let judgement = 'No'
  for (let i = 0; i < ar.length; i++) {
    const str = ar.join('')
    if (str === T) {
      judgement = 'Yes'
      break
    }
    ar.unshift(ar.pop())
  }
  console.log(judgement)
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'))
