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.

Solution in Common Lisp (SBCL 1.1.14) (judge verdict: Wrong Answer)

(defparameter *string* (concatenate 'list (read-line)))
(defparameter *answer* (concatenate 'list (read-line)))
(defparameter *length* (length *string*))
(if (loop :for k :from 0 :upto 5 initially (setf (cdr (last *string*)) *string*) thereis(equal (subseq *string* k (+ k *length*)) *answer*))
    (print "Yes")
    (print "No"))
