I wish the feedback from the error message was clearer, as it's not clear on which exact example the code fails.
I don't get the k+j < length part.. And the description makes it even more confusing if you have a number such as 19 in a an array of length 5 that automatically shouldn't be possible to an onion since 19 will always be bigger than the length?
JS: Node v14 should be used along with its appropiate assertion tools (Mocha + Chai). Refer to this and this

From the solutions I learn that an empty array is considered an onion array. This souds strange to me. Also arrays with an even number of elements are considered valid onion arrays whilst the tests/examples only show arrays with an odd nunmber of elements.

Python translation. Please, review and approve.
Can somebody explain me this please: "If all of the following are true: ... j + k = array.length - 1"
why is ([1, 2, 19, 4, 5]) an onion array? In my understanding, 1+5 = 6; but array.length - 1 would be 4?
So
[1, 2, 19, 4, 5].lengthis5, and[1, 2, 19, 4, 5].length - 1is4. Remember that indexing starts at zero, so[1, 2, 19, 4, 5][4]is the fifth element, which equals5.Does that answer your question?

PHP Translation Kumited - please carefully review and approve :D
Approved
The description could be clearer. This is more of a reading task than a programming task. People actually are submitting
O(n²)solutions. This may be what you want, or not.well, i don't have any performance benchmark. Because i don't see this kata jumping
7kyurating :)True.
But do you want it to be a moderately hard reading assignment, or an easy programming one?
(Either one works for me! :)
Yep, really hard to understand what's expected !
; ) )
suggest how it could be more readable ?
May be some examples would help :
ok, cool. I took two of your examples and added it. Hope that helps.
That makes it a lot clearer, without actually spelling out the solution.
j+k=length or j+k+1=length ?
one less than length of array :D
