# 
# 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`.
