We are given two strings, A and B.

A shift on A consists of taking string A and moving the leftmost character to the rightmost position. For example, if A = ‘abcde‘, then it will be ‘bcdea‘ after one shift on A. Return True if and only if A can become B after some number of shifts on A.

Example 1:
Input: A = ‘abcde‘, B = ‘cdeab‘
Output: true

Example 2:
Input: A = ‘abcde‘, B = ‘abced‘
Output: false

Note:

  • A and B will have length at most 100.
class Solution:
    def rotateString(self, A, B):
        """
        :type A: str
        :type B: str
        :rtype: bool
        """
        if not len(A) and not len(B):
            return True
        if not len(A) or not len(B):
            return False
        for _ in range(-1,len(A)):
            if A==B:
                return True
            A = A[1:] + A[0]
        return False
