Array - A data structure that stores an ordered list of items, with each item is directly accessible by a positional index. Linked List - A data structure that stores ordered list of items in nodes, where each node stores data and has a pointer to the next node. Bianary Search Tree - A data structure in which each node stores data and has up to two children, known as a left child and a right child. Hash Table - A data structure that stores unordered items by mapping (or hashing) each item ...
