Crate sudoku_solver

Sudoku solver library

This library provides a very simple backtracking algorithm for solving sudoku puzzles.

Example

use sudoku_solver::*;

fn main() {
    let board = Board::from(&[
        [0, 2, 0, 0, 0, 0, 0, 0, 0], // row 1
        [0, 0, 0, 6, 0, 0, 0, 0, 3], // row 2
        [0, 7, 4, 0, 8, 0, 0, 0, 0], // row 3
        [0, 0, 0, 0, 0, 3, 0, 0, 2], // row 4
        [0, 8, 0, 0, 4, 0, 0, 1, 0], // row 5
        [6, 0, 0, 5, 0, 0, 0, 0, 0], // row 6
        [0, 0, 0, 0, 1, 0, 7, 8, 0], // row 7
        [5, 0, 0, 0, 0, 9, 0, 0, 0], // row 8
        [0, 0, 0, 0, 0, 0, 0, 4, 0], // row 9
    ]);

    println!("Puzzle:\n{}\n", board);

    if let Some(solution) = solve(&board) {
        println!("Solution:\n{}\n", solution);
    } else {
        println!("No solution found.");
    }
}
