While the Node.js and testing portion of this project was rather straight forward, I have to say writing a sudoku solving algorithm tied me up for days. I was curious to hear from others if they were able to write an original algorithm, or if they had to google a workable solution (not copying code,…

[image] kinome79: how far were we expected to take this I think the puzzles you were asked to solve were enough. There is the idea of “gold plating” - building it better than it needs to be. If someone comes and asks you to write a function to return the if the current year is a leap year, y…

Thanks for the response. I do believe it said you needed to solve more than just the sample puzzles, and said we needed to come up with the logic, which suggested they didn’t want a lot of googling to determine the answer… The `solve` function should handle solving any given valid puzzle string, no…

[image] kinome79: Do you know if there is a non-backtrack solution? I mean, we’d have to build program in the logical methodologies that humans use to solve. Like, look singles in rows, columns, and nonets. Maybe you come up with a way to do Snyder notation. You figure out a way to look for x…

Yep, thats what the first 400 lines of mine does, got as far as building arrays of all possible values and comparing those for possible eliminations, but that code was so messy I assumed I was doing it wrong. I noticed when looking for guidance that previously for this project you were also expecte…

[image] kinome79: but that code was so messy I assumed I was doing it wrong. Yeah, that’s the tricky part about algorithms. Sometimes it takes some work to find the “sexy” solution.

I had to read the Wiki on Sudoku algorithms but I wrote the code myself. I would have never been albe to come up with that backtrack algorithm on my own lol

This is one of the most memorable challenges. I checked my post regarding it and it looks like in few days ill have a one year anniversary since I completed it. I recall i was very proud of it, as I managed to write the logic, altho this took great effort and lot of struggle. It is important to not…
