Length of Last Word Problem

Question

Given a string s consists of upper/lower-case alphabets and empty space characters ' ', return the length of last word (last word means the last appearing word if we loop from left to right) in the string.

If the last word does not exist, return 0.

Note: A word is defined as a maximal substring consisting of non-space characters only.

Example:

Input: "Hello World"
Output: 5

Answer 1

Just seprate every work and count the last word.

class Solution:     def lengthOfLastWord(self, s: str) -> int:         return 0 if len(s.split()) == 0 else len(s.split()[-1])

eg : ans = Solution()

ans.lengthOfLastWord("ab a")

Output-

1
