1603. Design Parking System

Easy

Design Simulation Counting

Problem Explanation

Explanation:

We can simply keep track of the number of available parking slots for each car type (big, medium, small) and decrement the count whenever a car of that type parks.
When a car tries to park, we check if there are available slots for that car type and return true if parking is successful.
The constraints ensure that we do not need to worry about exceeding the slot limits.

Solution Code

class ParkingSystem {
    private int[] slots;

    public ParkingSystem(int big, int medium, int small) {
        this.slots = new int[]{big, medium, small};
    }

    public boolean addCar(int carType) {
        if (slots[carType - 1] > 0) {
            slots[carType - 1]--;
            return true;
        }
        return false;
    }
}
