sudoku command line solver

We have hosted the application sudoku command line solver in order to run this application in our online workstations with Wine or directly.

Quick description about sudoku command line solver:

This tool written in C uses the Backtracking algorithm to solve Sudoku puzzles.
The idea was born by participating a coding challenge of a German internet forum.
https: //www.coding-board.de/threads/coding-herbst-die-coding-board-de-coding-challenge.39297/
So it's rather made for fun. However, this code won in terms of speed.

Unfortunately, the initiator of the contest has passed away in the meantime. R.I.P. Benjamin.
