58. Length of Last Word

Given a string s consists of some words separated by spaces, return the length of the last word in the string. If the last word does not exist, return 0.

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

Example 1:

Input: s = "Hello World"
Output: 5

Example 2:

Input: s = " "
Output: 0

Constraints:

• 1 <= s.length <= 104

• s consists of only English letters and spaces ' '.

public class Solution {
    public int LengthOfLastWord(string s) {
      return s.Trim().Split(' ').Last().Length;
    }
}
