class Solution {
    public int lengthOfLastWord(String s) {
        s= s.trim();
// this function will removes all the leading whitespaces from the String
int count = 0;
        for(int i = s.length()-1;i>=0;i--){
            if(s.charAt(i) == ' '){

            break;
            // this statement will break from this function aka this loop
            }
              count++;
        }
