/*
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 and goal consist of lowercase English letters.
*/
