my answer is 11.31, and I've drawn the picture, everything is right! could anybody tell me what the standard output is? what's your output? I think if the answer is 45.00, the fireball has ALREADY touched B, with only 2 touched of the wall!!!????!!!!
I output "45.00", and passed case 16...faint The direction of throw is selected such way that thrown fireball hits the target exactly after N collisions with the room walls. So (N+1)th collision is the collision with the target
I meant that the fireball should NOT touch B during the first N collisions. But in fact, I could. and that touch won't be considered a collision!!!!!!!!! |
