Design Parking System

class CarParkingSystem {
public:
    vector<int> slots;

    CarParkingSystem(int big, int medium, int small) {
        slots = vector<int>{big, medium, small};
    }

    bool parkCar(int type) {
        if (slots[type - 1] > 0) {
            slots[type - 1]--;
            return true;
        }
        return false;
    }
};

Design a car parking system using C++. The solution involves creating a CarParkingSystem class that manages three types of parking slots: big, medium, and small. Follow these steps to handle the parking logic:

1. Initialize the class with three parameters, big, medium, and small, to represent the number of slots for each car type.

2. Use a vector slots to dynamically store the counts of each type of parking slot.

3. Implement the parkCar method:

   • The method takes one parameter, type, denoting the car type (1 for big, 2 for medium, 3 for small).
   • Verify if there are available slots for the given type by checking if the corresponding value in the slots vector is greater than zero.
   • If a slot is available, decrement the slot count for that type and return true to indicate successful parking.
   • If no slots are available, return false.

This implementation effectively tracks the number of available parking spots for each car type and updates the availability dynamically as cars are parked.

class VehicleParkingSystem {

    int[] slotsAvailable;

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

    public boolean parkCar(int type) {
        if (this.slotsAvailable[type - 1] > 0) {
            this.slotsAvailable[type - 1]--;
            return true;
        }
        return false;
    }
}

This solution outlines a parking system for vehicles through the VehicleParkingSystem class implemented in Java. You manage three types of parking slots: big, medium, and small.

• Initialize VehicleParkingSystem by specifying the number of slots available for each type of vehicle:

int[] slotsAvailable;

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

• Attempt to park a car using the parkCar method, which takes an integer representing the type of car (1 for large cars, 2 for medium-sized cars, and 3 for small cars):

public boolean parkCar(int type) {
    if (this.slotsAvailable[type - 1] > 0) {
        this.slotsAvailable[type - 1]--;
        return true;
    }
    return false;
}

In the VehicleParkingSystem method, instantiate the array with the counts of available slots for each type. The parkCar method checks if the slot count for that specific type of vehicle is greater than zero. If so, it decrements the count and returns true to indicate the car was successfully parked. If not, it returns false, indicating the parking attempt was unsuccessful.

typedef struct {
    int openSlots[3]; // Slots for types of vehicles
} CarPark;

CarPark* createCarPark(int large, int medium, int compact) {
    CarPark* system = (CarPark*) malloc(sizeof(CarPark));
    system->openSlots[0] = large;
    system->openSlots[1] = medium;
    system->openSlots[2] = compact;
    return system;
}

bool addVehicleToPark(CarPark* system, int vehicleType) {
    if (system->openSlots[vehicleType - 1] > 0) {
        system->openSlots[vehicleType - 1]--;
        return true;
    }
    return false;
}

void destroyCarPark(CarPark* system) {
    free(system);
}

The C programming solution provided outlines a basic system to manage a parking lot with three types of parking spaces: large, medium, and compact. The primary components of this solution include structures and functions to handle the parking system's operations.

• Structure Definition: A CarPark struct is defined with an array openSlots to keep track of available slots for each vehicle type.

• Creating a Car Park: The function createCarPark(int large, int medium, int compact) initializes a CarPark with the number of available slots for each vehicle type as inputs. Memory allocation is handled using malloc, and the initial slot counts are set based on the provided arguments.

• Adding a Vehicle: The function addVehicleToPark(CarPark* system, int vehicleType) checks if there is available space for the specified type of vehicle (large, medium, compact). Vehicle types are input as integers (1 for large, 2 for medium, 3 for compact). If space is available, it decrements the count of open slots for that vehicle type and returns true. If no spaces are available, it returns false.

• Destroying a Car Park: To clean up resources, destroyCarPark(CarPark* system) is used to free the allocated memory for the parking system.

Use this implementation for straightforward parking management in applications that need to handle various vehicle sizes without dependencies on external libraries or complex data structures.

var CarPark = function(large, medium, compact) {
    this.slots = [large, medium, compact];
};

CarPark.prototype.parkCar = function(type) {
    if (this.slots[type - 1] > 0) {
        this.slots[type - 1]--;
        return true;
    }
    return false;
};

Create a simple car parking system using JavaScript to manage parking slots for large, medium, and compact cars. The CarPark function initializes the parking lot with a preset number of slots for each type of car. The parkCar method is then used to park a car based on its type, decrementing the available slots accordingly and returning a success status.

• Define the CarPark constructor that takes three parameters: large, medium, and compact. These parameters represent the number of available slots for each car type.

  javascript Copy

  var CarPark = function(large, medium, compact) {
      this.slots = [large, medium, compact];
  };
  

• Add the parkCar method to the CarPark prototype. This method takes the type of car (1 for large, 2 for medium, 3 for compact) as a parameter.

  javascript Copy

  CarPark.prototype.parkCar = function(type) {
      if (this.slots[type - 1] > 0) {
          this.slots[type - 1]--;
          return true;
      }
      return false;
  };
  

This implementation efficiently tracks the number of available parking slots for each type of car and indicates whether a car can be parked in the respective slot. This system is particularly useful for parking management in locations like malls and offices, ensuring an organized distribution of parking spaces according to car size.

class ParkingManager:

    def __init__(self, large: int, medium: int, compact: int):
        self.slots = [large, medium, compact]

    def parkCar(self, type: int) -> bool:
        if self.slots[type - 1] > 0:
            self.slots[type - 1] -= 1
            return True
        return False

The solution implements a ParkingManager class in Python to manage a parking system for three types of parking spots: large, medium, and compact. The class provides two main functionalities:

1. Initialize parking capacities:

   • During the initialization (__init__), it takes three integers representing the number of slots available for large, medium, and compact cars respectively. These values are stored in a list named slots.

2. Parking a car:

   • The method parkCar accepts an integer (type) as input, which corresponds to the car type (1 for large, 2 for medium, and 3 for compact).
   • It checks if there is an available slot for the specified car type. If available, it decrements the count of that slot type by one and returns True, indicating the car was successfully parked.
   • If no slots are available for the given type, the method returns False.

This setup provides a straightforward method to manage parking within a system with specified capacities for different types of cars. The class can easily be integrated into a larger system where car parking operations are needed.
