Thank you I hope this answer stays up because it's something newbies like me may not notice after figuring out this problem.

Yeah sometimes I see that the problem makers and the leaders/mod on this page have attitudes that are not the nicest... I guess it doesn't pay to be nice that's why.
Opitt has a very good hint I think

I have no idea. This kata is so weird... I feel like maybe codewars have better problems in other languages and not SQL

I think you should also allow the order by # of the item listed in the querry instead of just strictly saying "order by comma"...

bro this code is high level for such a simple kata. Much respect.

Python with its False being equal to 0 is just the worst for this problem.

Best practice for that logic

Wow this solution really click in my mind! Thank you for the insightful comment.

Thank you so much, you put it so clearly to understand, I learned something new today! Greatly appreciated!

Every programmer should know some fundamental mathematics!
This is for sure the optimal solution to this problem.

Hello I saw the comments for the problem but I do not quite understand what n=0 means in the parameter. I know that not setting n=0 will raise an error, would you (or somebody) mind explaining that to me please? Thank you kind person!

yeah I happened to have the same solution too, what a coincidence :))
