linked list CORRECT ANS-data structure that stores *ordered* list of items in nodes, where
each node stores data and has a pointer to the next node; can have multiple subitems
binary tree CORRECT ANS-A data structure that consists of nodes, with one root node at
the base of the tree, and two nodes (left child and right child) extending from the root, and
from each child node
can have no children, single left or right, or both right and left
hash table CORRECT ANS-data structure that stores *unordered* items by mapping (or
hashing) each item to a location in an array
max-heap CORRECT ANS-a tree that maintains the simple property that a node's key is
greater than or equal to the node's childrens' keys
stack CORRECT ANS-ADT which items are only inserted on or removed from the top of a
stack
LIFO
Queue CORRECT ANS-ADT in which items are inserted at the end of the queue and
removed from the front of the queue
FIFO
deque ("deck") CORRECT ANS-ADT in which items can be removed at both the front and
back
