- OpenAIMediumApplied ScientistExtensible card-hand ranking: three of a kind, flush, pair and a discard rule
A three-part object-oriented coding exercise built around a card game: rank hands by three of a kind, pair and high card, insert a flush category, then add a discard rule that removes hands that are not a pair, returning a log of each game. It tests extensible design, deterministic tie-breaking and absorbing rule changes cleanly.
