Reverse Words in a String

题目描述

Given an input string, reverse the string word by word.

For example, Given s = "the sky is blue", return "blue is sky the".

注意要用s.split(), 不要pass任何参数，这样连续的whitespace都会被去掉

Solution

class Solution(object):
    def reverseWords(self, s):
        """
        :type s: str
        :rtype: str
        """
        return " ".join(map(lambda x : x[::-1], s[::-1].split()))
