/*

Expand code in the two Solution sections with the following changes:

    1. Create a specialization of the vehicle class called "Truck".

    2. Add a boolean property, "SupportsTrailer" to the Truck class.

    3. Override the Seats property so that it always returns 2.

    4. Create another specialization of the vehicle class called "Motorcycle".

    5. Create an enum, "MotorcycleModelType". The enum should have the following values: Tourer, Sport, Racing.

    6. Add a property of type MotorcycleModelType to the Motorcycle class with the name "ModelType".

    7. Add two instances of the Truck class to the "vehicles" list. Name one instance "Scania" and give it four wheels with diameter 19. Name the other instance "Volvo" and give it two wheels with diameter 18 and two wheels with diameter 20.

    8. Add two instances of the Motorcycle class to the "vehicles". Name one instance "Suzuki" and give it two wheels with diameter 17. Name the other instance "Honda" and give it one wheel with diameter 16 and one wheel with diameter 17.

    9. Order the vehicles list by the size of the smallest wheel on each vehicle.

Print the vehicles list as JSON to the console.
