CSCI 340 Exam 2Binary Tree ANS✔✔ A binary tree consists of a finite set of nodes that is
either empty, or consists of one specially designated node called the root of the
binary tree, and the elements of two disjoint binary trees called the left subtree
and right subtree of the root.
Complete Binary Tree ANS✔✔ The depth d is the strictly binary tree all of
whose leaves are at level d.
The total number of nodes in a complete binary tree of depth d equals 2d+1 - 1.
Since all leaves in such a tree are at level d, the tree contains 2d leaves and,
therefore, 2d - 1 internal nodes.
Almost Complete Binary Tree ANS✔✔ Each leaf in the tree is either at level
d or at level d - 1.
For any node nd in the tree with a right descendant at level d, all the left
descendants of nd that are leaves are also at level d.
Array and Linked Binary Tree ANS✔✔
