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
andB
will have length at most100
.
