A playing card is a string Suit-Rank, such as Hearts-10 or Spades-A. There are four suits (Clubs, Diamonds, Hearts, Spades) and thirteen ranks (3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A, 2), giving a standard 52-card deck.
Implement a class Deck representing one such deck. Each test gives a sequence of operations and checks what each returns.
Examples
Example 1
Input: init =
[], operations =[["order",[]]]Output:
[["Clubs-3","Diamonds-3","Hearts-3","Spades-3","Clubs-4","Diamonds-4","Hearts-4","Spades-4","Clubs-5","Diamonds-5","Hearts-5","Spades-5","Clubs-6","Diamonds-6","Hearts-6","Spades-6","Clubs-7","Diamonds-7","Hearts-7","Spades-7","Clubs-8","Diamonds-8","Hearts-8","Spades-8","Clubs-9","Diamonds-9","Hearts-9","Spades-9","Clubs-10","Diamonds-10","Hearts-10","Spades-10","Clubs-J","Diamonds-J","Hearts-J","Spades-J","Clubs-Q","Diamonds-Q","Hearts-Q","Spades-Q","Clubs-K","Diamonds-K","Hearts-K","Spades-K","Clubs-A","Diamonds-A","Hearts-A","Spades-A","Clubs-2","Diamonds-2","Hearts-2","Spades-2"]]Explanation: Cards are sorted by rank first and suit second. Ranks run 3, 4, ..., 10, J, Q, K, A and then 2, so the deck starts with the four 3s (Clubs, Diamonds, Hearts, Spades) and ends with the four 2s.
