A C++ library for generating, validating, solving, checking, etc Sudoku puzzle.

make sudoku

./sudoku 

• Create Header files

As what it stated ...

• Reorganize code using OOP approach

This is my first CPP project, I don't think I wrote OOP code properly.

• Optimised code for performance

The function 'SudokuSolution()' is an enhanced version of leetcode - Sudoku solver . My code might not be that optimised in terms of performance.

• Rename variable

I wrote this in a rush , some variable is not named properly and are not consistent. rename it with meaningful variable name

• Testing

Testing is important. Any testing framework is fine but personally prefer bash scripting to test out the function.

• Better output format

Print it properly? Probably it will be ideal that I could see obvious changes to show the border of 3x3 box.

• documentation

Provide Documentation on each function on what it does. Please also provide documentation on elaboration on the algorithm especially for SudokuSolution() and initialize()

Please discuss in issues and I will assign the issues to you. Once it is assigned,

1. fork the repo
2. open a draft Pull Request

Speical thanks to めぐ in Leetcode Warrior community to provide help in fixing a bug when designing the algorithm of SudokuSolution() which return the number of unique solution that a sudoku board has.
