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

LeetCode OJ supports Python now!

The solution for this problem is extremely easy... What you need is only three build-in methods: string.split(), string.join(), and list.reverse().

class Solution:

    # @param s, a string

    # @return a string

    def reverseWords(self, s):

        res = s.split()

        res.reverse()

        return " ".join( res )

That is it...
