Create a text file which name starts with sudoku. The program supports multiple files so you can make as many as you want.
Example: sudoku.txt, sudoku_test.txt or sudoku board.txt
The file should be placed in the same directory as solver.py
Fill the text file with input data so that you have 9 lines, 9 characters each. For empty field you can use any character that is not a space. Can be . or 0 if you want.
So that this...
.2...43..
9...2...8
...6.9.5.
........1
.725.368.
6........
.8.2.5...
1...9...3
..98...6.
...gives this (in the image below there will always be dots even if you used a different character):
┏━━━━━━━━━┳━━━━━━━━━┳━━━━━━━━━┓
┃ . 2 . ┃ . . 4 ┃ 3 . . ┃
┃ 9 . . ┃ . 2 . ┃ . . 8 ┃
┃ . . . ┃ 6 . 9 ┃ . 5 . ┃
