What is a binary tree in data structure? A binary tree is a tree-type non-linear data structure with a maximum of two children for each parent. Every node in a binary tree has a left and right reference along with the data element. ... The nodes that hold other sub-nodes are the parent nodes. A parent node has two child nodes: the left child and right child.What are binary trees used for? A binary tree is a type of data structure for storing data such as numbers in an organized way. Binary search trees allow binary search for fast lookup, addition and removal of data items, and can be used to implement dynamic sets and lookup tables.What makes a tree binary? A binary tree is made of nodes, where each node contains a "left" pointer, a "right" pointer, and a data element. The "root" pointer points to the topmost node in the tree. ... The nodes at the bottom edge of the tree have empty subtrees and are called "leaf" nodes (1, 4, 6) while the others are "internal" nodes (3, 5, 9).What is Binary Tree explain with example? Definition: A binary tree is either empty or consists of a node called the root together with two binary trees called the left subtree and the right subtree. The nodes of a binary tree can be numbered in a natural way, level by level, left to right. ... For example, see Figure 4.5.Can a binary tree be empty? A (mutable) binary tree, BiTree, can be in an empty state or a non-empty state: When it is empty, it contains no data. When it is not empty, it contains a data object called the root element, and 2 distinct BiTree objects called the left subtree and the right subtree.
