Sudoko Solver

I find Sudoko lame. Any "puzzle" that can be solved algorithmically and without creativity isn't worth the time. So I wrote a solver.

Building

Any reasonably modern C++ compiler should work. It works with gcc 6.4 and clang 3.6.2 for sure. Compilation is trivial:

g++ sudoku.cpp -o sudoko

or

clang++ -std=c++11 sudoku.cpp -o sudoku

Running

It reads the "puzzle" from stdin. There are examples in the test subdirectory. Error checking is minimal. But it's like this:

sudoku < test/test1.dat

I'm already bored, that's enough.
