 * File Description: Problem 43
 * panacloud-modern-global-apps/typescript-node-projects
 * 
 * 
 * Unchanged Magicians: Start with your work from Exercise 40. 
 * Call the function make_great() with a copy of the array of magicians’ names. 
 * 
 * Because the original array will be unchanged, return the new array and
 * store it in a separate array. 
 * 
 * Call show_magicians() with each array to show that you have 
 * one array of the original names and one array with the Great added to each magician’s name.
 * 
 * Call show_magicians() to see that the list has actually been modified.
