设停车场是一个可停放 n 辆汽车的狭长通道，且只有一个大门可供汽车进出。汽车在停车场内按车辆到达时间的先后顺序，依次由北向南排列（大门在最南端，最先到达的第一辆车停放在车场的最北端）。若停车场内已经停满 n辆车，那么后来的车只能在门外的便道上等候。一旦有车开走，则排在便道上的第一辆车即可开入。当停车场内某辆车要离开时，在它之后进入的车辆必须先退出车场为它让路，待该辆车开出大门外，其他车辆再按原次序进入车场。每辆停放在车场的车在它离开停车场时必须按它停留的时间长短缴纳费用。试为停车场编制按上述要求进行管理的模拟程序。-A parking lot can park n vehicles is a narrow channel, and only one gate for cars in and out.Car in the parking lot vehicle in the order of arrival time of　north to south in order to arrange (gate at the southern tip of the first to arrive the extreme north of the first car parked in the yard).If any parking lot with n car, the later the car have to wait outside the door of the pavement.Once you have a car drive away, ranked first car can drive into the sidewalk.When a car in the parking lot to leave, after it into the vehicle must withdraw　the yard to make way for the it, opened the car door, other vehicles to enter the yard according to the original order.Every car parked in the yard when it left the parking lot must be pay fees it stay for the length of time.Try for parking lot according to the above requirements management simulation program
