class Solution(object): def reverseWords(self, s): """ :type s: a list of 1 length strings (List[str]) :rtype: nothing """ s = ' '.join([word[::-1] for word in (''.join(i for i in s))[::-1].split()])
and also why change input type from str to list of chars, which make trouble form coding : )
And my code is not pythonic, anyone have list comprehension solution
class Solution(object): def reverseWords(self, s): """ :type s: a list of 1 length strings (List[str]) :rtype: nothing """ #if len(s) == 0: # return ''; s.reverse() start,n= 0, len(s) for i in range(len(s)): if s[i]==' ': s[start:i]=s[start:i][::-1] start = i+1 s[start:n]=s[start:n][::-1]
it got WA on case "a b", which local ouput "b a", which is correct, but OJ output "a b"
You have to modify the given list, referenced by
s, not make
s reference something else. That's only your local variable, the caller can't even see it.
ok, I know. python str is immutable, which would make parameter be list of chars, same as java. But my python code is not pythonic, do you have list comprehension solution: )
I don't see a good way to use list comprehension, but maybe you'll like this solution of mine.
