The output of your program must match the format illustrated in this example.

Here are some other additional requirements for this program:

You may assume that phone number contains no spaces.

After a deletion, there is no record currently selected

Each record (first name, last name and phone number) must be stored as an object. These objects must be stored in a Linked List.

The Linked List must be kept sorted at all times based on last name. Sorting is to be achieved when an insertion or modification is done. NO SORTING ROUTINE IS ALLOWED. ALWAYS INSERT A NEW RECORD OR EDITED RECORD INTO ITS' CORRECT PLACE IN THE LINKED LIST. Note: Changing the last name will require resorting.

Use as many generic algorithm as you can.

// Make another class named userList
