At only 20 minutes for such a complicated description, I think you did very well for someone who is not a native English speaker. I am always amazed by the English skills of people from so many different places on Codewars.

Now that you have figured out the kata, can you suggest exactly how to improve (clarify) specific parts of the description? I am open to suggestions, as always.

I find the description messy, convoluted and very hard to interpret. It took me 20 minutes to finally understand the task.

Thanks for the feedback. Yeah, I was surprised myself that it was rated that way. Maybe it's because people seem to have some trouble understanding the description, though I made it as clear as I could.

this is a nice kata but too easy for 6kyu IMHO.

agree, this should be max 6kyu

didn't cross my mind... thanks

just use console.log?

in JS, my code passed all the tests except this one: 'expected 6i, instead got '0'' (in the more complex tests).
Could you share the input for this test, as i have been unable to find the problem.
Thanks
