Design a parking system for a parking lot. The parking lot has three kinds of parking spaces: big, medium, and small, with a fixed number of slots for each size.
ParkingSystem(int big, int medium, int small)Initializes object of the
ParkingSystemclass. The number of slots for each parking space are given as part of the constructor.
bool addCar(int carType)Checks whether there is a parking space of
carTypefor the car that wants to get into the parking lot.
carTypecan be of three kinds: big, medium, or small, which are represented by
3respectively. A car can only park in a parking space of its
carType. If there is no space available, return
false, else park the car in that size space and return
Input ["ParkingSystem", "addCar", "addCar", "addCar", "addCar"] [[1, 1, 0], , , , ] Output [null, true, true, false, false] Explanation ParkingSystem parkingSystem = new ParkingSystem(1, 1, 0); parkingSystem.addCar(1); // return true because there is 1 available slot for a big car parkingSystem.addCar(2); // return true because there is 1 available slot for a medium car parkingSystem.addCar(3); // return false because there is no available slot for a small car parkingSystem.addCar(1); // return false because there is no available slot for a big car. It is already occupied.
0 <= big, medium, small <= 1000
