We have a truck, which can carry at most $N$ kilograms.
We will load bricks onto this truck, each of which weighs $W$ kilograms. At most how many bricks can be loaded?
Input is given from Standard Input in the following format:
Print an integer representing the maximum number of bricks that can be loaded onto the truck.
Each brick weighs $3$ kilograms, so $3$ bricks weigh $9$ kilograms, and $4$ weigh $12$ kilograms.
Thus, we can load at most $3$ bricks onto the truck that can carry at most $10$ kilograms.
