设有一个可以停放n辆汽车的狭长停车场，它只有一个大门可以供车辆进出。车辆按到达停车场时间的早晚依次从停车场最里面向大门口处停放（最先到达的第一辆车放在停车场的最里面）。如果停车场已放满n辆车，则后来的车辆只能在停车场大门外的便道上等待，一旦停车场内有车开走，则排在便道上的第一辆车就进入停车站。停车站内如有某辆车要开走，在它之后进入停车场的车都必须先退出停车站为它让路，待其开出停车场后，这些车辆再依原来的次序进场。每辆车在离开停车场时，都应根据它在停车场内停留的时间长短交费。如果停留在便道上的车未进停车场就要离去，允许其离去，不收停车费，并且仍然保持在便道上等待的车辆的次序。编制一程序模拟该停车场的管理。-Long, narrow parking lot with a park n cars, it is only one door can be used for vehicle access.
