A simple and efficient Python application that solves standard 9x9 Sudoku puzzles automatically using the backtracking algorithm.
- Reads the initial Sudoku board directly from a text file (
sudoku.txt). - Solves complex puzzles using recursion and constraint checking (Backtracking).
- Displays both the initial unsolved puzzle and the final solved solution clearly in the terminal.
- Python (Core logic and file handling)
