Exactly! The task description doesn't imply that using RegExp naively (i. e. taking "searchText" as a valid regular expression) should work. Still, those RegExp-based solutions are being upvoted, but hey, that's life... ;)

They need a "cute" option lol

You mean why it hasn't got a lower rating, don't you? I guess it's because one needs to cope with the broadly advertised "inappropriate wording" of the kata... ;)

Thanks! Description fixed.

Hi, nice and challenging kata :) There is only one small issue:

Its description states that columns 'visits_count' and 'when_happened' should be returned, although it requires them to be returned in reverse order. I know that the order is not explicitly specified, but still, they should be listed in the expected order to make a ninja happy... :)

Yeah, superb that someone made a benchmark on this :) I would say that the results confirm the idea that just simply filling in the 1-s "in a spiral" should be faster than doing some more complex operations with lists etc. (as can be seen in some other solutions). Moreover, for me, this solution is maybe the most readable / comprehensible... :)

This one seems older according to the comments' timestamps. (It's a shame that Codewars doesn't display some "date of creation" right at a kata, or does it?)

lol. totally. honestly not sure, codewars wont show who voted.

I'm sorry, but who could upvote this interesting, but still quite crazy (the boxes function!), solution as a best practice? :D

Well, yes, impressive etc. :) But I guess the performance level requirement for passing this kata forces nearly everyone to program such a solution in the end... :)
