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
Explanation :
After performing 2 shifts we can achieve the goal string from string s. After the first shift the string s is => bcdea. After the second shift the string s is => cdeab.

Example 2

Input : s = "abcde", goal = "adeac"
Output : false
Explanation :
Any number of shift operations cannot convert string s to string goal.

Example 3

Input : s = "abcde", goal = "abcde"
Output : true

Constraints

• 1 <= s.length <= 100
• 1 <= goal.length <= 100
• s and goal consist of only lowercase English letters.
