Could you please check again?

I mean the code which is correct but does not pass tests.

Can you post the code which errors out?

Rankings are "immutable". Let's move on.

So you're downvoting author's work because other users thought it should be 4kyu? I don't see how that's relevant.

Kata ranks can't be changed.

What exactly are you suggesting?

It is fixed.

The flipped output is still an issue tough

• Well, Thanks lecso2 , for notifying
• I'm not a Kotlin Expert, But I've tried to fix the situation, Hope this makes it works if so You Could resolve the raised issue
• Sorry for that late response Regards .. Zizou

Yes, it is. MrZizoScream can you fix it?

Actual and expected are flipped in random tests, your function is returning the wrong value there.

I agree. Once I read the explanation on Google under the name "Connect the ropes" I had no problem solving it. I think you should update the explanation part

Not a kata issue, in a row means next to each other, not in the whole string.
Also, why 80 coudln't be LXXX if it says no more than 3 and there are only 3 X there?

No, because it's listing only the numbers of interest, not all k. As you can see, 0 squared doesn't contain 1.

You are right. Due to a Codewars bug, a StackOverflowError was ignored and the tests passed. We'll add a workaround in the tests. This will mean that your solution and one or two others won't pass anymore. :-( Thanks a lot for reporting this!
