Design Parking System

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.

•   class ParkingSystem {
        // Variables to track available parking spaces for each type of car
        int big, medium, small;
  
        // Constructor to initialize the number of parking spaces for each car type
        public ParkingSystem(int big, int medium, int small) {
            this.big = big;       // Number of spaces available for big cars
            this.medium = medium; // Number of spaces available for medium cars
            this.small = small;   // Number of spaces available for small cars
        }
  
        // Method to add a car of the specified type
        public boolean addCar(int carType) {
            // Check if there are no available spaces for the given car type
            if ((carType == 1 && !(big > 0)) || 
                (carType == 2 && !(medium > 0)) || 
                (carType == 3 && !(small > 0))) {
                return false; // Return false if no space is available for this car type
            }
  
            // Decrement the corresponding parking space count based on the car type
            if (carType == 1) {
                big--; // Decrease big car spaces
            } else if (carType == 2) {
                medium--; // Decrease medium car spaces
            } else {
                small--; // Decrease small car spaces
            }
  
            return true; // Return true if the car was successfully parked
        }
    }
  
    /**
     * Example usage:
     * ParkingSystem obj = new ParkingSystem(big, medium, small);
     * boolean param_1 = obj.addCar(carType);
     *
     * - `big`, `medium`, and `small` specify the initial number of spaces for each type of car.
     * - `carType` is 1 (big), 2 (medium), or 3 (small).
     * - The `addCar` method returns true if a car of the given type can be parked, false otherwise.
