Hint
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.
Implement the ParkingSystem class:
ParkingSystem(int big, int medium, int small)Initializes object of theParkingSystemclass. 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 ofcarTypefor the car that wants to get into the parking lot.carTypecan be of three kinds: big, medium, or small, which are represented by1,2, and3respectively. A car can only park in a parking space of itscarType. If there is no space available, returnfalse, else park the car in that size space and returntrue.
Example 1:
Input
["ParkingSystem", "addCar", "addCar", "addCar", "addCar"]
[[1, 1, 0], [1], [2], [3], [1]]
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.
Constraints:
0 <= big, medium, small <= 1000carTypeis1,2, or3- At most
1000calls will be made toaddCar
