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, l;
    char s[120], t[120], c;
    gets(s);
    gets(t);
    l=strlen(s);
    for(i=0; i<l; i++)
    {
        if(strcmp(s, t)==0){
            printf("Yes\n");
            return 0;
        }
        c=t[l-1];
        for(j=l-1; j>=0; j--)
        {
            t[j]=t[j-1];
        }
        t[0]=c;
    }
    //printf("%s\n", t);
    printf("No\n");

    return 0;
}
