  Problem Name : Design Parking System
  Problem URL : https://leetcode.com/problems/design-parking-system/
  Description :
    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:
    
    1. ParkingSystem(int big, int medium, int small)
    2. bool addCar(int carType)
    
  Difficulty : Easy
  Language : C#
