Your previous Plain Text content is preserved below:

For this coding exercise, I ask that you do the following:

Implement a deck of cards.

- The deck must contain 52 cards
- Each card can be one of four suits (Hearts, Spades, Diamonds, Clubs)
- A card can also be one of 13 values (1, 2, 3, ...Jack, Queen, King)
- I should be able to shuffle the deck of cards
- I should be able to draw one card from the top of the deck
