题目：
Given an input string, reverse the string word by word.
For example,
Given s = "
return "
代码：oj在线测试通过 Runtime: 172 ms
思路：
把中间多个空格考虑去除了就OK了
最后用strip()函数把首位的空白去了

class Solution:
# @param s, a string
# @return a string
def reverseWords(self, s):
words = s.split(' ')
if len(words) < 2 :
return s
tmp = ""
for word in words:
word = word.replace(' ','')
if word != "" :
tmp = word + " " + tmp
tmp = tmp.strip()
return tmp思路：
