Rotate String

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.

Example Testcases:

"abcde"
"cdeab"
"abcde"
"abced"
