A standard deck has 13 values on the face of the card:

• Ten “Number Values”, starting at the Ace “A”, and going up to 10.
• Three “Face Values”, which are the Jack, Queen, and King.

A standard deck of playing cards are divided into four suits, which are also grouped into colors:

• Red:
• Diamonds
• Hearts

• Black:
• Spades
• Clubs

A doubly linked list is nearly similar to a singly linked list, as it is a list of structs, where each struct has a pointer to the next struct in the list.

However, in a doubly linked list, each struct also has a pointer which points to the last struct in the list. This means functions can be used to go back and forth through the list, instead of just going one way.
