Description

Design a ParkingSystem for a lot with three space sizes: big, medium, and small. Implement the class:

- ParkingSystem(int big, int medium, int small) initializes the lot with a fixed number of spaces for each size.

- bool addCar(int carType) parks a car in a space of its type (1=big, 2=medium, 3=small) if one is available, returning true, or false if all matching spaces are full.

Example 1:

Input

["ParkingSystem", "addCar", "addCar", "addCar", "addCar"]

[[1, 1, 0], [1], [2], [3], [1]]

Output

[null, true, true, false, false]

Example 2:

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.

Code

class ParkingSystem:

    def __init__(self, big: int, medium: int, small: int):
        

    def addCar(self, carType: int) -> bool:
        


# Your ParkingSystem object will be instantiated and called as such:
# obj = ParkingSystem(big, medium, small)
# param_1 = obj.addCar(carType)

class ParkingSystem:

    def __init__(self, big: int, medium: int, small: int):
        

    def addCar(self, carType: int) -> bool:
        


# Your ParkingSystem object will be instantiated and called as such:
# obj = ParkingSystem(big, medium, small)
# param_1 = obj.addCar(carType)
