Step Three Write a main program that will use your PiggyBank class. It will ask the user for the name of a file. The file will begin with an integer indicating the number of PiggyBanks described in the file. Each PiggyBank will be represented by 4 numbers which indicate the number of quarters, dimes, nickels, and pennies, respectively. For example, this file describes 4 PiggyBanks (the first has 4 quarters, 1 dime, 0 nickels, 25 pennies, etc.)

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'.
