/**
|
|
* Game of 3-D Plot
|
|
* <p>
|
|
* Based on the BASIC game of 3-D Plot here
|
|
* https://github.com/coding-horror/basic-computer-games/blob/main/87%203-D%20Plot/3dplot.bas
|
|
* <p>
|
|
* Note: The idea was to create a version of the 1970's BASIC game in Java, without introducing
|
|
* new features - no additional text, error checking, etc has been added.
|
|
*
|
|
* Converted from BASIC to Java by Darren Cardenas.
