This kata is about drop_while, not filter.

Come back when you've learnt to read the specifications, because obviously you don't and you're acting arrogantly like as if you do perfectly. You don't, so just shut up and don't bring yourself even more shame than you already have brought upon yourself.

(Yes, I'm being harsh there because of FUDs around beginner 8kyu katas and the annoying players of CodeWars Fun: Arrogance. My gentleness is reserved for the more deserved people who actually know what they're doing.)

You're misunderstanding how drop_while works.

Looks like you need to study more on 8kyu katas ;-)
