LeetCode344. Reverse String

Write a function that takes a string as input and returns the string reversed.

Example 1:

Input: "hello"
Output: "olleh"

Example 2:

Input: "A man, a plan, a canal: Panama"
Output: "amanaP :lanac a ,nalp a ,nam A"

思路：差不多应该去做做medium了

class Solution:
    def reverseString(self, s):
        """
        :type s: str
        :rtype: str
        """
        return s[::-1]

 可以复杂点。（为了学习join()和reversed()方法）

       return ''.join(reversed(s))
