Is there anyway someone can lead me to a doc as to explain whats going on in this solution? I solved it but my code looks very procedural in comparison and I'm always trying to learn new things. Thanks.

Is there someone I can ask about how this works? It's one of the few katas I've skipped over and want to gain an understanding for it. I can read how the hashes translate over, but I'm unfamiliar with the rest of the code.

Great solution. I originally was wondering how you got the increments to work then I broke down your variables and figured it out. Nicely done!~

I like this solution the best, very readable and straightforward. Great job!

Thank you for that, I was able to add the additional code to make it work because of your tip on Sudoku.

For the "and work with int arrays" test case, perhaps add another out-of-order integer lower than 3, to prevent a loophole for that particular case.

Other than that, great challenge. I learned quite a few new things. Thank you for the kata!

Looks so much more readable than mine T-T I want to cry xD Well done!

I believe many new rubyist will find this a good exercise to learn about indices, it was a nice refresher for me.

Might be wrong but doesn't the n x n in the details of the Ruby version mean it's a square?

Can someone explain how this solution works?

The background and goal for this kata made this super enjoyable. Picked up a few things I wasn't really thinking about before. Thanks!
