You are asked to develop a mobile application for a customer. The customer will provide you with the requirements. Your job is to code the application and provide unit tests to verify that the application meets the customer’s requirements. For this milestone, you will focus on delivering the contact services. The purpose of these services is to add, update, and delete contact objects within the application. The contact service uses in-memory data structures to support storing contacts (no database required). In addition, there is no user interface for this milestone. You will verify the contact service through JUnit tests. The contact service contains a contact object along with the contact service. The requirements are outlined below.
Contact Service Requirements
The contact service shall be able to add contacts with a unique ID.
The contact service shall be able to delete contacts per contact ID.
The contact service shall be able to update contact fields per contact ID.
The following fields are updatable:
firstName
lastName
Number Address
This code needs to be done in Java and does not need a user interface since it is using JUnit testing. This portion just needs to read example information with each requirement mentioned above.

Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should not be added to the list). these values entered by the user are added to a list we call 'initial_list'. then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. finally, inside print out all of the values in the new list. for example: input: enter value to be added to list: a enter value to be added to list: b enter value to be added to list: c enter value to be added to list: exit output: a b c a b c a b c note how 'exit' is not added to the list. also, your program needs to be able to handle any variation of 'exit' such as 'exit', 'exit' etc. and treat them all as 'exit'.
