A standard card deck includes 52 different cards, evenly distributed over four suits: 13 clubs (♣), 13 diamonds (♦), 13 hearts (♥) and 13 spades (♠). Clubs and spades are black, whereas diamonds and hearts are red. Each suit includes thirteen ranks: two through ten (with each card depicting that many symbols of its suit), jack, queen, king (each depicted with a symbol of its suit) and ace (depicting a single symbol of its suit). Commercial card decks may also include anywhere from one to six jokers, but we do not take these into account here.
Each card of a standard 52-card deck is represented by a string (str) that contains the rank of the card, followed by its suit:
ranks: 2, 3, 4, 5, 6, 7, 8, 9, 10, J (jack), Q (queen), K (king) and A (ace)
suits: C (clubs; ♣), D (diamonds; ♦), H (hearts; ♥) and S (spades; ♠)
As such, the ace of spades is for example represented as AS, the ten of hearts as 10H and the king of clubs as KC.
Write a function deck that takes no arguments. The function must return a (list) containing a random shuffle of the representations of all 52 cards in a standard card deck.
