### 直白解法一： ###

class ParkingSystem {
    public:
        int b,m,s;
        ParkingSystem(int big, int medium, int small):b(big),m(medium),s(small){}
        
        bool addCar(int carType) {
           if(carType == 1 && b > 0) return b-->0;
           else if(carType == 2 && m > 0) return m-->0;
           else if(carType == 3 && s > 0) return s-->0;
           return false;
        }
    };
    
    /**
     * Your ParkingSystem object will be instantiated and called as such:
     * ParkingSystem* obj = new ParkingSystem(big, medium, small);
     * bool param_1 = obj->addCar(carType);
     */

### Hash解法二： ###

class ParkingSystem {
        Map<Integer, Integer> map=new HashMap<>();
        public ParkingSystem(int _big, int _medium, int _small) {
          map.put(1, _big);
          map.put(2, _medium);
          map.put(3, _small);
        }
        
        public boolean addCar(int carType) {
          if( map.get(carType) > 0){
              map.put(carType,map.get(carType)-1);
              return true;
          }
          return false;
        }
    }
    
    /**
     * Your ParkingSystem object will be instantiated and called as such:
     * ParkingSystem obj = new ParkingSystem(big, medium, small);
     * boolean param_1 = obj.addCar(carType);
     */

还有一个二进制解法 没看懂emmmm  再去学学C++语法
