The best structures to create the following items are

ARRAYHASHMAPS  QUEUE SORTED LINK LISTS

Explanation:

The best structures to create the following items are:

Array : for the storage of cards in a card game the best data structure to be used should be the Array data structure. this is because  the size of the data ( 52 cards ) is known and using Array will help with the storing of the cards values in the Game.Hashmaps : Hashmap data structure should be implemented in online shopping cart this IS BECAUSE  items can be easily added or removed from the cart therefore there is a need to map the Items ID or name to its actual database online waiting list are usually organised/arranged in a first-in-first-out order and this organization is best created using the queue data structure Sorted link lists is the best data structure used to create, store and manage online tickets. the sorted link data structure helps to manage insertions and deletions of tickets in large numbers  and it also reduces the stress involved in searching through a large number of tickets by keeping the tickets in sorted lists
