reverseWordsInString

word[::-1] is the most efficient way to reverse a string - don't do stack append + pop into helper, although that's faster than reversed(word)

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