Показать описание
In this video we are solving a popular Microsoft interview question: Reverse Words in a String.

This is a medium level question on Leetcode but really it's quite simple and just involves some string parsing. Realistically the only tricky part is dealing with the fact that there can be multiple whitespaces in the string but otherwise it's smooth sailing.

Guys it looks like ‘i-1’ isn’t needed, , y solution passes all test cases when I submit it without that line! Thanks so much, Cush cracking faang for the vid! You probably see me commenting on all your vids now!

Hey, Can someone explain the purpose for the i -= 1 after parsing the string builder? Shouldn't it anyway iterate forth to the next if it encounters a whitespace?

why can't we simply do this-:
class Solution:
def reverseWords(self, s: str) -> str:
words = s.split()
return ' '.join(reversed(words))
