Case contract

Input: a comma-separated hold'em range string. Tokens: pairs "77", "77+" (up to AA), "TT-77"; non-pairs "AKs"/"AKo"/"AK" (no suffix means both suited and offsuit), "A9s+" (kicker rises to one below the top card), "A9s-A6s" (inclusive). Whitespace around tokens is ignored. Duplicated classes count once. Return total combos: pair 6, suited 4, offsuit 12.

Why this case matters

Range combo counts drive equity, frequency and blocker arithmetic in solvers and trackers.
