Sudoku solver

3x3 Sudoku solver with customizable rule and board shape.

Standard code

Compiling

To compile it to build directory, using ninja as build tool:

mkdir build
cmake -GNinja -B build
ninja -C build

Running

Running the sample:

./build/sudoku < sample/1.sudoku

Customizing the rule

To customizing the rule simply edit src/main.cpp. But if you want to keep it separate just copy main.cpp to new file, for exmple src/custom.cpp, then rerun the cmake with additional variable:

cmake -GNinja -B build -DMAIN=src/custom.cpp

then rebuild as usual:

ninja -C build
