An airport van shuttles passengers between the terminal and the parking garage. After 4 trips, the tank is empty, and the van needs to drive to the gas station. After it has been refilled, it will drive to the terminal. The behavior of the car depends on two states: its location (terminal, garage, or gas station), and the tank level (empty or not). Complete the following class. The constructor yields a van in the garage with a full tank.
