Sample Output

The vehicle is in chamber $(0,0).$

The ore in this chamber is $2\mathrm{.}3$ tons.

Load the ore? $(\frac{y}{n})$:$y$

The ore in this chamber is $2\mathrm{.}3$ tons.

Enter the amount to load: $2\mathrm{.}3$ tons.

Input one of these choices $(\frac{N}{S}\frac{?}{?}\frac{E}{W})$:$E$

That is the valid exit!

You are now in chamber $(1,0).$

The ore in this chamber is $4\mathrm{.}8$ tons.

Load the ore? $(\frac{y}{n})$:$y$

Enter the amount to load: $3\mathrm{.}5$ tons.

Input one of these choices $(\frac{N}{S}\frac{?}{?}\frac{E}{W})$:$N$

That is the valid exit!

You are now in chamber $(1,1).$

The ore in this chamber is $1\mathrm{.}7$ tons.

Load the ore? $(\frac{y}{n})$: $n$

Input one of these choices $(\frac{N}{S}\frac{?}{?}\frac{E}{W})$ : W

That is the valid exit!

You are now in chamber $(0,1).$

The ore in this chamber is $3\mathrm{.}4$ tons.

Load the ore? $(\frac{y}{n})$:$y$

Enter the amount to load: $5\mathrm{.}3$ tons.

That amount is more than the ore in this chamber!

Enter the amount to load: $1\mathrm{.}4$ tons.

Input one of these choices $(\frac{N}{S}\frac{?}{?}\frac{E}{W})$:$N$

Not a valid exit for chamber $(0,1).$ The valid exit is: $S$

Input one of these choices $(\frac{N}{S}\frac{?}{?}\frac{E}{W})$ : $S$

That is the valid exit!

You are now in chamber $(0,0)$

The amount of ore in the vehicle is: $7\mathrm{.}2$ tons.
