1603. Design Parking System Easy

1/**
2 * [1603] Design Parking System
3 *
4 * 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.
5 * Implement the ParkingSystem class:
6 * 
7 * 	ParkingSystem(int big, int medium, int small) Initializes object of the ParkingSystem class. The number of slots for each parking space are given as part of the constructor.
8 * 	bool addCar(int carType) Checks whether there is a parking space of carType for the car that wants to get into the parking lot. carType can be of three kinds: big, medium, or small, which are represented by 1, 2, and 3 respectively. 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 true.
9 * 
10 *  
11 * Example 1:
12 * 
13 * Input
14 * ["ParkingSystem", "addCar", "addCar", "addCar", "addCar"]
15 * [[1, 1, 0], [1], [2], [3], [1]]
16 * Output
17 * [null, true, true, false, false]
18 * Explanation
19 * ParkingSystem parkingSystem = new ParkingSystem(1, 1, 0);
20 * parkingSystem.addCar(1); // return true because there is 1 available slot for a big car
21 * parkingSystem.addCar(2); // return true because there is 1 available slot for a medium car
22 * parkingSystem.addCar(3); // return false because there is no available slot for a small car
23 * parkingSystem.addCar(1); // return false because there is no available slot for a big car. It is already occupied.
24 * 
25 *  
26 * Constraints:
27 * 
28 * 	0 <= big, medium, small <= 1000
29 * 	carType is 1, 2, or 3
30 * 	At most 1000 calls will be made to addCar
31 *
