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 main(), 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
