using System;

public class Program
{
   public static int LengthOfLastWord(string str) {
        return str.Trim().LastIndexOf(' ') == -1 ?
            str.Trim().Length : str.Trim().Length - str.Trim().LastIndexOf(' ') - 1;
    }

    public static void Main(string[] args)
    {
        string input = "java c# go javascript rust";
        
        Console.WriteLine("The length of the last word is: " + LengthOfLastWord(input));
