Thanks! :)

Yes, in the homepage and in your profile discourse section.

Are the replies to solutions somehow visible to people who have not yet solved the kata?

Yea, this is strange. It passes other test cases, it's only failing on tests marked "Should work for random arrays". So for random array arr => [71,66,23,31,64,30,24,19,56,9,14,53,62,5,27,33,4,57,58,16,68,47,21,38,78,70,7,50,76,28,55,73,32,8,35,37,72,13,17,59,74,20,77,40,69,61,6,65,18,63,1,2,54,25,11,43,29,36]
The test returns: ✘ Expected: '', instead got: '1-2, 4-9, 11, 13-14, 16-21, 23-25, 27-33, 35-38, 40, 43, 47, 50, 53-59, 61-66, 68-74, 76-78'

So as a test, I returned '' in my code and all (20) test cases for "Should work for random arrays" passed. And the others failed. Which I expected.
Example: arr => [39,25,48,29,14,30,28,49,52,38,17,47,53,51,37,16,10,4,7,5,35,33,23,42,60,8,13,59,34,6,11,19,45,15,50,1,54,31,43,3,46,18,20]

            ✔  Test Passed: Value == ''

This is weird. I will try again and see if I have better luck.

That is strange; I am taking the array you gave and running it through the same function that Codewars should be running it through behind the scenes, and it's turning up correctly. I will look at my test cases and ensure everything looks correct.

The random cases are run through a loop however, so it's imaginable that if there's an issue with one there'd be an issue with them all. Are you passing some random test cases before this happens or does it happen on the first one?

EDIT: I just tried it again and it works. I know Codewars has been buggy for me all day (assigning servers and such), and since the random arrays are generated by a function that should be preloaded in the execution order, maybe it's not being executed serverside by Codewars?

I'm failing the random test cases and I can't figure out what the issue is. For example, on Input array: [27,13,12,29,53,41,24,20,19,40,44,31,5,36,25,50,15,22,30,26,17,21,11,32,38,43,46,34,18,14,39,35,3,51,33]
I get the following failure message:
Expected: '', instead got: '3, 5, 11-15, 17-22, 24-27, 29-36, 38-41, 43-44, 46, 50-51, 53'

Why is it expecting an empty string? What am I missing?

Thanks Steve!!

Hi BK - my mistake. I'd tweaked the code for the test cases and accidentally reverted to the old maximum values. This should be fixed now - give it another spin.

Hi Steve,
I see in a thread below, you were going to limit the max values of n and l to 100 and 15 respectively in the random tests. Has this been done?
I am attempting the kata in javascript. The test fails on big numbers. Example input: n=84 and l = 64.

Interesting kata. That "no loop" restriction threw me off.
