I realize these comments are quite old, but @DworkinFromChaos is right.

Specifications don't belong in the (mutable!) fields of the kata. They should be in the description, perhaps especially in the case where they cause otherwise working solutions to fail.

Approved :)

C# translation ready! Please review and approve.

Kotlin translation

Haskell translation

Fix approved and new example added to description

Fixed this for my translations (all except Python yet) and proposed kumites (awaiting for approve):
JS,
TS,
Coffee,
PHP,
Ruby

This probably invalidates most of the solutions, so they should be revalidated.

UPD: Python

All languages: missing edge case tests with empty arrays.
