796 - Rotate String.

Easy

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.
