    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.
