We have an interface called discount strategy, that calculates discounts for a simple parking management software. It has two sub-classes that implement different discount strategies. 1. DUAffilatedFriday discounts - make discounts for DUAffilated car type on Fridays 2. SUVFriday discounts - make discounts for SUV car type on Fridays These two classes check the car type and day of the week and implement a certain discount strategy. 1. Use a factory pattern to reimplement the entire code as-is. 2. Use a main method to test your code
