Description

Given two strings s and goal, return true if and only if s can be transformed into goal by performing some number of left-shift operations on s.

A left-shift moves the leftmost character of s to its rightmost position.

- For example, applying one left-shift to s = "abcde" produces "bcdea".

Example 1:

Input: s = "abcde", goal = "cdeab"

Output: true

Example 2:

Input: s = "abcde", goal = "abced"

Output: false
