Reverse Words in a String III

Intuition

• Have to join via a ’ ’ at the end

Complexity

Runtime

$O(N)$

Space

$O(N)$

Code

class Solution:
    def reverseWords(self, s: str) -> str:
        split = s.split()
        res = []
        for word in split:
            res.append(word[::-1])
        return ' '.join(res)

Using Reversed

class Solution:
    def reverseWords(self, s: str) -> str:
        split = s.split()
        res = []
        for word in split:
            res.append(''.join(list(reversed(word))))
        return ' '.join(res)
