General information
This tool allows you to solve default (9 x 9) sudoku tables.
Solution based on recursive function that builds series of “assumptions”
and finds first one that doesn’t conflict with sudoku game rules. Also
tool uses binary representation of known (7 → 001000000b) and unknown
(1 or 2 or 6 → 000100011b) numbers for simplifying solution process.
Warning! This method always finishes with some result (it is finite). But in some cases it can take some time. This behavior is correct for the application.
