Hi,

• no random tests
• no sample tests
• the description is incorrect (there is no stdin/out thing, here)

If you're interested in authoring kata, you really should begin with reading the entire documentation about it. Otherwise it will just turn out as a bad experience for you, I'm afraid.

Unpublishing
