/**
 * I own a parking garage that provides valet parking service.
 * When a customer pulls up to the entrance they are either rejected
 * because the garage is full, or they are given a ticket they can
 * use to collect their car, and the car is parked for them.
 *
 * Given a set of different parking bays (Small, Medium, Large),
 * write a control program to accept/reject cars (also small, medium or large)
 * as they arrive, and issue/redeem tickets.
 *
 * Garage layout is 1 small bay, 1 medium bay, and 2 large bays: [1,1,2]
 *
 * First sequence Actions:
 * [(arrival, small),
 * (arrival, large),
 * (arrival, medium),
 * (arrival, large),
 * (arrival, medium)]
 *
 * Expected output: [1, 2, 3, 4, reject]
 *
 * Second sequence Actions:
 * [(arrival, small),
 * (arrival, large),
 * (arrival, medium),
 * (arrival, large),
 * (depart, 3),
 * (arrival, medium)]
 *
 * Expected output: [1, 2, 3, 4, 5]
