Problem
Given two strings s
and goal
, return true
if and only if s
can become goal
after some number of shifts on s
.
A shift on s
consists of moving the leftmost character of s
to the rightmost position.
- For example, if
s = "abcde"
, then it will be"bcdea"
after one shift.
Example 1:
Input: s = "abcde", goal = "cdeab" Output: true
Example 2:
Input: s = "abcde", goal = "abced" Output: false
Constraints:
1 <= s.length, goal.length <= 100
s
andgoal
consist of lowercase English letters.
