|
| I know there are a couple of solutions in Perl that are written in 2-3
| lines of code ... but their methodology is brute force and I find that
| inelegant so I went back to my original solution and added three more
| layers of sophistication.
|
| I haven't been able to find a puzzle that can defeat it but I am hoping
| someone can. If you want to try ... www.psoug.org and click on PSOUG
| Sudoku Challenge in the bottom right quadrant.
|
| Create two tables (sudoku and possibles) followed by three functions and
| a single procedure.
|
| Now I know the code needs a huge amount of cleaning up, bind variables,
| more use of NDS, put it all into a package, etc. but before I spend
| time on that I am hoping someone will beat it into submission.
|
| Let the game begin.

Why PL/SQL? It can be done with just SQL.

Let the game bounce.
