Reverse Words in a String

Problem: Reverse Words in a String

Just split the sentence into words, reverse them and combine back.

Code in Python:

class Solution(object):
    def reverseWords(self, s):
        """
        :type s: str
        :rtype: str
        """
        words = s.split(" ")
        res = ""
        for word in words[::-1]:
            if word: res += word + " "
        return res[:len(res)-1]
