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
arc

Sample Output 2

No

abc does not equal arc after any number of operations.

Sample Input 3

aaaaaaaaaaaaaaab
aaaaaaaaaaaaaaab

Sample Output 3

Yes

#include<stdio.h>
#include<string.h>
int main()
{
	int i,j,n;
	char s[101],t[101],a;

	scanf("%s%s",s,t);

	n=strlen(s);
	for(i=0;i<n-1;i++){
		if(strcmp(s,t)==0){
			printf("Yes\n");
			return 0;
		}
		a=s[n-1];
		for(j=0;j<n;j++){
			s[n-1-j]=s[n-2-j];
		}
		s[0]=a;
	}
	printf("No\n");
	return 0;
