This little prog in C++ solves sudoku. If the debug version does not say 'UFF...', then you gave it too easy set to solve. ;)

Don't use this for cheating. ;P

As usual - input file format should be obvious. If not, use the source, Luke! ;]

Installation:

1. untar into an empty directory

2. make test

3. cp sudoku{,-dbg} /usr/bin/ (or wherever you want it)
