This kata is challenging enough. Most of 6 kyu kata I could write shorter. I think it can be shorter than I wrote but I gave up to find the shorter one.

Thank you.

I've never known about class RegExp in Kotlin. I used to user class Regular only. How to import class RegExp in Kotlin?

I removed the note and modified the prolog. Please see again the desciption.

Ok.

I think, it shouldn't Eight Queens Puzzle but N Queens Puzzle, because the size not only eight but N.

I have no idea to solve this problem. :(

Sure. I just wanna make it faster than my previous one.

Perhaps you can try other algorithms to solve this kata.

Duplicate with?
