:D If I was confident I wouldn't somehow break the kata, I'd add this in. Been a few years since I wrestled with Codewars' ways! Glad you enjoyed it.

Nice, though I would've added this ;)

Too late to change, and this is not a good idea at all.

I was really struggling with this one. Should be ranked little bit higher in my opinion (4kyu). I found Sudoku solver (3kyu) way easier...
But in the end I think it's a really cool Kata! Thanks for this one.

I'm getting frustrated by this kata :D ...
Could come one give me advice on the adding and removal of "-"
characters in the TAB, I'm trying an aproach jumping string by string ...

unfortunately, ranking isn't modifiable (anymore) after approval.

A nice kata with a very thoughtful set of tests. Considering the difficulty of much of the 6 kyu katas, this one might be a good fit for being 5 kyu.

JohanWiltink, i just thought that removing that detail from the spec would add a little more challenge/fun to the kata. I didn't want in any way to deliberately misguide anyone.

I thought it was a logical step to return the entire alphabet when an empty string is passed as input, but clearly that's not true for the people that are trying to solve the kata.

I'll change the spec.

At this point it does not make any sense to pass an empty string as input, i'll pass only lowercase letters.

Hadn't read this before posting above.

I just changed my vote on this kata.

If you willfully hide booby-traps in a kata, you're going against everything I hold dear. Specifications should be complete; there is no place for surprises.

Adding the puzzle tag feels quite misplaced on this kata. You're just unwilling to write complete specs, and it's unclear to me why. This is not a puzzle.

Nice one!

Looked straight forward at first sight. Was a bit of "whack-a-mole". Fixed one test case only to break another one. Took me to test three different approaches to find a solution.

Thanks!

No language specified. Issue not reproducible. Closing.

no problem. Though, as I said, that might not be a good idea to introduce that... :o

of course, do not change the kata for that. Was just asking

I reckon the last of those three makes the most sense, in terms of the slides on each string occurring together. I'll have to test it though to see what my code spits out... oh god. I'll do it when I'm feeling brave/at my computer.

Oh boy, not sure. To be honest, I don't really know if there are definite rules for how tabs are laid out in monospace. I prefer the look of the right hand version in terms of viewing the start of the beat, so inclined to let it be...
