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

package main

import "fmt"

func main() {
	var s, t string
	fmt.Scan(&s, &t)

	for i := 0; i < len(s); i++ {
		first := s[0 : len(s)-1-i]
		second := s[len(s)-1-i:]
		tmp := second + first
		if tmp == t {
			fmt.Println("Yes")
			return
		}
	}
	fmt.Println("No")
}
