Thank you.
So is there any way this level may evolve ?

I would like to, but i don't find the option, don't know how to do it.
Can someone help me with that ?

Thank you for reminding me, Done :-)

Well, then with imports allowed, the kata seems good to me as it is. I agree it would be too simple without the string manipulation. Removing duplicates in solution is not very hard and doesn't feel weird to me. I added my satisfaction (sorry i forgot till now). I would add a ranking if it was possible, i couldn't (because of draft mode i guess). I would say 6 kyu, what do you think ? I'm still not very confident with the ranks. I've read in the wiki that you'd need 10 votes then, and you have 5...

Hi rge123,
Thanks for letting me submit. I've learned something nice now, didn't know about numpy roots !
About the errors I had, i haven't been able to reproduce them, but i know it was not related to repeated solutions (because i had those too !).
I agree that the hard version would be a nightmare, and certainly a bigger one for the checking code than for the solution maker. There could be so many different answers.
So maybe not the best idea.
But, a way to make your kata more difficult, could be to disable imports.
Implementing a math method like the solving of cubic equations, even though the method is easy to find on the web, is a good exercise.
Then, about the question of the string business, i don't know. It's not very hard and quite satisfying, ...
Do you know why the kata is stuck at beta stage ?

All right, got it, thanks.

So for the author:
The only issue i've had while solving: the solution checker sometimes took the members of my solution in a wrong order, because (i think) of the rounding precision of the imaginary part of complex numbers. But somehow this problem disappeared, maybe you changed the testing code ?
My opinion on the kata : it's a very good idea to propose a cubic equations solver kata. But the way you propose it feels like two different katas : one to reorganise the initial string, and another to actually solve a cubic eq.
The reorganisation part is fun, but a little strange, because only based on addition/subtraction and sides of equation. A complete reorganising kata with a wider range of inputs would be more challenging (maybe there's already one on Codewars ?).
The solving part is great, it needs a flexible solution checker with forgiving rounding. An idea then, could be to add a harder version, asking to give exact solutions, using fractions, roots and/or trigonometry.

Thank you Blind4Basics,
I found the kata on the creator's profile.
What is the way to cooperate on a kata in draft mode ?

Hi,
I have a correct solution, test and attempt all passed fine, but i can't submit.
Is there a reason for that or is that a bug ?
It's the first time it happens to me.

Nothing stupid in your questions for me, my decription is short and would certainly deserve a picture. That was my first kata, i like the problem, but the kata creation is not very good. I wasn't aware of the codewars_test toolbox. So yes, it only tells when a test fails.

Hi, the ground doesn't count as a barrier, each room needs a panel for its ground too.
And ceiling/floor can be shared as well between piled neighbors.

Hi,
I've Created this kata:
https://www.codewars.com/kata/5e9ce15e9a872f002dc6dc94
There are several things i don't understand: I was hesitating how to rate its difficulty, and set it first at 5 kyu. But a friend told me it should really be 3 kyu. I modified it, and it now appears in the kata search engine only when looking for a 5 kyu kata, even though it's labelled as a 3 kyu.
Much worse : The stats are indicating that it's been completed 5 times, but i can see only two solutions : mine and Voile's now invalid one. I know from a friend that he's solved it. Why can't i see other solutions ?
Stats again, say that the kata has been satisfying for 38% users out of 4 !!! No need to be a great problem solver to detect that there might be a problem to solve here.
So, please help me, is there something i've done wrong or misunderstood ?

Hey Voile,
I would like to understand, maybe you can help me:
I see the stats say that my kata has been completed 5 times, but there are only two solutions, yours and mine, how is that possible. And it says that 38% out of 4 have given a positive vote, well i don't know how many votes that is ??? My question is where are the negative votes coming from if none seem to have solved the kata ?
Also, is that possible to remove your solution now that I fixed the test cases ?
Thanks for your time :-)

Thank you, done !
