[1603] Design Parking System

看來是個歡樂題，那就不糾結了QQ

typedef struct {

int big;

int mid;

int small;

} ParkingSystem;

ParkingSystem* parkingSystemCreate(int big, int medium, int small) {

ParkingSystem *Park = calloc (1, sizeof (ParkingSystem));

Park->big = big;

Park->mid = medium;

Park->small =small;

return Park;

}

bool parkingSystemAddCar(ParkingSystem* obj, int carType) {

if (carType ==1)

{

if (obj->big <= 0)

return false;

obj->big--;

}

else if (carType==2)

{

if (obj->mid <= 0)

return false;

obj->mid--;

}

else if (carType==3)

{

if (obj->small <= 0)

return false;

obj->small--;

}

else

return false;

return true;

}

void parkingSystemFree(ParkingSystem* obj) {

free(obj);

}

/**

* Your ParkingSystem struct will be instantiated and called as such:

* ParkingSystem* obj = parkingSystemCreate(big, medium, small);

* bool param_1 = parkingSystemAddCar(obj, carType);

* parkingSystemFree(obj);
