//prompt >> count the length of last word
//the input >> string, output >> number
//if no last word, there should just be a 0

var lengthOfLastWord = function(s) {
    //if argument is not being passed as a string
    if (typeof s !== 'string') {
        return 0;
    }
    
    //get the input to be divided individually so we can identify each element
    var words = s.split(' ');
