Case contract

Input: five distinct cards as rank+suit strings; ranks 2-9, T or 10, J, Q, K, A (case-insensitive), suits c/d/h/s (case-insensitive). Return the standard five-card category name in lower case; A-2-3-4-5 is a straight; royal flush is reported as "straight flush".

Why this case matters

Poker engines settle real money pots from these comparisons; a single misranked hand pays the wrong seat.

One recorded failure
