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.

LIFO and FILO are both used to describe ways to insert and retrieve data from a data structure.

LIFO stands for Last in First Out, which means the last element to be put into the data structure is the first to be retrieved.
