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: Wrong Answer)

const main = function(input){
  var lines = input.split("\n");
  var s = lines[0];
  var t = lines[1];
  var can = false;
  
  for(var i=0;i<s.length;i++){
    if(s ===t){
      can = true;
      break;
    }
    var last = s.slice(s.length-1,s.length);
    s = last + s.slice(0,-1);
    console.log(last,s);
  }
  if(can){
  	console.log("Yes");
  }else{
  	console.log("No");
  }
  
  
}


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