Overview

Newdoku

Simple Sudoku solver written in Rust. Method is inspired by a method briefly outlined in a CS lecture I had that I decided to try and implement based only on my understanding from the lecture.

It is called Newdoku because I started doing this a while ago and forgot about it and decided to restart, hence "New"

Quick Start

$ cargo run
OPTIONS:
    -f, --file     Load Sudoku from file
    -h, --help           Print help information
    -q, --quiet          No output until finished solving (faster)
    -s, --step     Wait STEP millis between inserts [default: 0]

When loading from a file, the parser parses any digit as a number in the sudoku. Any other character other than a newline will be parsed as an empty square.

Example sudoku: xxxxxxx9xx9x7xx21xxx4x9xxxxx1xxx8xxx7xx42xxx5xx8xxxx748x1xxxx4xxxxxxxxxxxx9613xxx
