Sudoku solver [prog]

[Phibrizzo]

Hello

This time something different.
I did sudoku solver. If you have a problem with sudoku, use this program
I used "brute force" and recursion method. But is fast (as a Gigatron).
Time of solving may be different for different combination of digits.

Usage:
Coursors - move the coursor
A button - change and put digits
B button - clear all
START button - start solving

Minium config:
32kB, ROMv5a - not tested,
On 64kB ROMv5a/v6 works very well.

Nice.

Many thanks!

Just s small suggestion. Maybe use a different color of the manually entered digits, than the program solved ones?

I think, it is possible.
Give me a little time for this.

Edit:
Little fix. Sometimes solution is not possible. Some combination of digits is unsolvable.
I was forgot information about that. Now is ok.
