+*  I am going to convert the string to an array based on the space character that      *
+*  separates each word. Then I am going to loop through each word in the array and     *
+*  capitalize the first letter of the word. I am going to convert array back to a      *
+*  string to return as the answer.

+*    1) Convert string to arry of words by splitting on space.                         *
+*    2) Loop thru each word in the array and convert first letter to uppercase         *
+*       using the charAt(0) value and then appending the remainder of the word         *
+*       using the slice() function                                                     *
