Working the problems from the following web site:
Note: No solution PDFs are contained within this repo; this repo contains only source code solutions.
Obviously the completed solutions will run to produce the correct answer to problems. That isn't the
purpose of me sharing this - the purpose is to share possible solutions. 

Note of efficiency: Some of these programs are quite efficient at solving the problem but most are
not -- there are more efficient programs out there if that is what you are seeking. My efforts mainly
focus on architecture and maintainability.
