we need better random test generators (EDIT: javascript fixed and random tests updated)

and you should, this is a 4 kyu after all

But probably not after this kata being approved.

ofc, you can change the tests if that's needed.

That's not intended but I guess I can't do anything with it 😂

My solution is faster than that, so I guess I can further raise n or make timer stricter.

But probably not after this kata being approved.

Your solution will stay. Those solutions were not intended.

FYI, my optimized solution takes < 0.5 sec for both 3 secs tests.

I won't give this kata a math label.
All you need is something that will be taught in a dsa lecture.
So it's not hard, I suppose.
