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

int main(void){
  char str1[100],str2[100],tmp;
  int i,j;
  scanf("%s",str1);
  scanf("%s",str2);
  for(i=1;i<strlen(str1);i++){
    if(strcmp(str1,str2)==0){
      printf("Yes");
      return 0;
    }
    for(j=(strlen(str1)-1);j>=-1;j--){
      if(j==(strlen(str1)-1)){
        tmp=str1[j];
      }else if(j==-1){
        str1[j+1]=tmp;
      }else{
        str1[j+1]=str1[j];
      }
    }
  }
  printf("No");
  return 0;
