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 -
sandgoalconsist of lowercase English letters.
SOLUTION:
class Solution:
def rotateString(self, s: str, goal: str) -> bool:
if len(goal) == len(s) and goal in s + s:
return True
return False
