Sudoku is a simple CLI program for generating random sudoku boards and solving sudoku boards (formerly a high school homework).
A C# .NET Framework CLI application for generating and solving sudoku boards. The generation and solving steps are done recursively using backtracking approach.
If the program won't have any specified command line arguments, it will generate a random board with all numbers visible.
- -f [path] to specify path to an unsolved board file, where each row will be on different line and unsolved values will contain non-numeric character
- -o [path] to specify output file of a solved/generated board
- -d [number] specify randomness of generating empty spaces (bigger value, more empty spaces)
- -h help
Example: sudoku.exe -f input.txt
