Trick-Taking Round

Score a round of a four-player trick-taking card game in which every player follows a fixed plan.

Four players sit in seats 0, 1, 2, 3; play passes from seat s to seat (s + 1) % 4. Each card is a two-character string: a rank from 7 8 9 T J Q K A (lowest to highest in that order) followed by a suit from C D H S, such as TH or AS. Every player holds the same number of cards, and hands[s] lists seat s's cards in the order the player prefers to play them.

The round is a sequence of tricks until the hands are empty. In a trick every player plays exactly one card:

• The leader (seat leader for the first trick) plays the first card still in their hand. Its suit is the led suit.
• The other players follow in seat order. A player who still holds a card of the led suit must play the first such card in their list. A player with none plays the first card still in their hand, whatever its suit.
• Winning: if any card of the trump suit was played, the highest trump wins. Otherwise the highest card of the led suit wins. Cards of any other suit never win. All cards in a trick are distinct, so there are no ties.
• The winner leads the next trick.

Scoring: the winner of a trick collects the card points of its four cards: A = 11, T = 10, K = 4, Q = 3, J = 2, and 0 for 9, 8, 7. The winner of the last trick also gets a bonus of 10.

Input: hands, four lists of cards of equal length; trump, one of "C", "D", "H", "S", or "N" meaning there is no trump suit; leader, the seat that leads the first trick.

Output: a list of four integers, the total points collected by each seat.
