Thanks for explaning that, I wish the person who made the kata would make that clear.

the instructions say: return in reverse order.
But the solution as follows should equal [0, 2, 9, 3, 9, 8, 2, 6, 7, 5, 4]
so how is this reverse order? if it was reversed order, should not be [9,9,8,7,6,4,2,2,0]

How come this kata is not deleted yet? That can discourge a begniner, who might think they are stupid or coding not for them. This kata is a joke.

I feel like an idiot now !! that's what happened when you take 2 days off coding. Thank you so much.
On a side note, do you know how I can change username? everytime I try to update it, It does not work.

Such a bad description.

Newbie questions: If I want to understand how to solve a kata like that. What topics should I know about or study? Thanks

I agree, the description is very confusing.

Please use spolier alert !!
