Ball Past the Window
A ball is dropped from height h, and after each bounce it rises to bounce times its previous height. Write bouncing_ball to count how many times the ball is visible from a window at height window: once while falling, then again on each upward and downward pass. If the input is invalid — h <= 0, bounce is not between 0 and 1, or window >= h — return -1.
