Length of Last Word

https://leetcode.com/problems/length-of-last-word/

Given a string s consisting of words and spaces, return the length of the last word in the string.

A word is a maximal substring consisting of non-space characters only.

Example 1:

Input: s = "Hello World"
Output: 5
Explanation: The last word is "World" with length 5.

Example 2:

Input: s = "   fly me   to   the moon  "
Output: 4
Explanation: The last word is "moon" with length 4.

Example 3:

Input: s = "luffy is still joyboy"
Output: 6
Explanation: The last word is "joyboy" with length 6.

Solution:

The solution for this problem is simple stupid:

  public int lengthOfLastWord(String s) {
    String[] words = s.split(" ");
     
    return words[words.length-1].length();
  }

But if you don't want to use standard mechanisms, you can add a pointer and find the last space in the string. And then calculate the distance.
