Playing cards are again represented as tuples of (rank,suit) as in the cardproblems.py lecture example program. In trick taking games such as whist or bridge, four players each play one card from their hand to the trick, committing to their play in clockwise order starting from the player who plays 0irst into the trick. The winner of the trick is determined by the following rules: If one or more cards of the trump suit have been played to the trick, the trick is won by the highest ranking trump card, regardless of the other cards played. If no trump cards have been played to the trick, the trick is won by the highest card of the suit of the 0irst card played to the trick. Cards of any other suits, regardless of their rank, are powerless to win that trick. Ace is the highest card in each suit. Note that the order in which the cards are played to the trick greatly affects the outcome of that trick, since the 0irst card played in the trick determines which suits have the potential to win the trick in the 0irst place. Return the winning card for the list of cards played to the trick.
