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.

Solution

class Solution:
    def rotateString(self, s: str, goal: str) -> bool:
        for i in range(len(s)):
            if s[i:] + s[:i] == goal:
                return True

        return False
