Sudoku Solver Go

  Terminal view of running our program

Inspiration

When I was learning Recursion and Backtracking back in 2021, I wrote a Sudoku solver in Java that takes input in CLI and solves it to print it again in CLI. After a year, when I saw this challenge on GHW, I thought let's make the solver again using recursion in Golang.

What it does

It takes a unsolved Sudoku pattern and solves it using recursion and backtracking.

How I built it

I used Go and my DS & Algo knowledge to make it work.

Challenges we ran into

A big for me while making it, was parsing the input to a 2D slice of integer [][]int. In Java, it is called 2d array. I had low knowledge of Scanners, Readers in Go and therefore it was a day to learn those and implement it accordingly.

What I learned

1. Better Understanding of Go.
2. Parsing byte data into another form.
3. Revised Recursion and Backtracking .

What's next for Sudoku Solver Go

I am planning to parse the input from any pictures to Go [][]int and in future I can host it also with some beautiful web pages using Go, HTML, CSS and JS. Also, I am gonna write a blog on hashnode about building a solver using Go.
