Given an input string, reverse the string word by word.
For example,
Given s = "the sky is blue
",
return "blue is sky the
".
class Solution:
def reverseWords(self, s):
if s is None or s == ‘‘:
return ‘‘
temp_list = s.split()
t = ‘‘
for i in range(len(temp_list)-1, -1, -1):
t += temp_list[i]
t += ‘ ‘
t = t[:len(t)-1]
return t
if __name__ == ‘__main__‘:
a = Solution()
print a.reverseWords(‘the sky is blue‘)
