why example 1:
1 1 1

See problem statment: "If the instruction tells the robot to go outside the room, the robot ignores this instruction."

Let's start from the point (1, 1, 1). After first move we will be at the same point (because we can't go outside the room at point (1, 2, 1)). And so on... After all we will be in the position (1, 1, 1). That is the only possible final position. So answer is 1.

Can you please explain why sample input 3 is 13*12*10 or it will solve the task ?

You can simply write program to check all possible starting points, so you will see that true answer is :)
