* https://github.com/coding-horror/basic-computer-games/blob/main/13_Bounce/bounce.bas
* Direct conversion from BASIC to Rust by Pablo Marques (marquesrs).
* No additional features or improvements were added. As a faithful translation,
* many of the code here are done in an unrecommended way by today's standards.
