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 long1=0, long2=0;
	char a[100];
	char b[100];
	int i, j;
	char tmp;
	printf("文字列を入力\n");
	scanf("%s", a);
	printf("文字列を入力\n");
	scanf("%s", b);
	long1 = strlen(a);
	long2 = strlen(b);
	if (long1 != long2) {
		printf("No\n");
	}
	for (i = long1 - 1; i >= 0; --i) {
		tmp = a[i];
		for (j = i - 1; j >= 0; --j) {
			a[j + 1] = a[j];
		}
		a[j + 1] = tmp;
	}
	if (strcmp(a, b) == 0) {
		printf("Yes\n");
	}
	else {
		printf("No\n");
	}
	return 0;
