Write a program that allows the user to enter any number of names. Your prompt can inform the user to input their first name followed by a space and last name. Order the names in ascending order and display the results with the last name listed first, followed by a comma and then the first name. If a middle initial is entered, it should follow the first name. Your solution should also take into consideration that some users may only enter their last name (one name).
