Solution of the Above Question

class Solution {

public:

    int lengthOfLastWord(string s) {

            int counter=0;

            int test=0;

            for(int i=0; i<s.length(); i++) {

                if(s[i]!=' '){

                    counter++;

                    test =counter;

                }

                else{

                    counter=0;

                }
