1603 - Design Parking System.

Easy

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 the ParkingSystem class. 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 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.

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 <= 1000
  • carType is 1, 2, or 3
  • At most 1000 calls will be made to addCar
