Chapter 19: Problem 1

The first node in a binary tree is called the __________.

Short Answer

Expert verified
Answer: The first node in a binary tree is called the "root."

Step by step solution

01

Understanding Binary Trees

A binary tree is a data structure in which each node can have at most two child nodes, typically referred to as the left child and the right child. These trees are a widely-used data organization technique in computer science and programming. The structure begins at a single starting point, which is the node we need to identify.
02

Identifying the First Node in a Binary Tree

The first node in a binary tree is the starting point from which all other nodes in the tree branch out, either to the left or to the right. This node is called the "root" of the tree.
03

Final Answer

The first node in a binary tree is called the "root."

Most popular questions from this chapter

Imagine a tree in which each node can have up to a hundred children. Write an analogue of the TreeNode declaration that can be used to represent the nodes of such a tree. A declaration such as TreeNode int value: { TreeNode "child 1 TreeNode "child?: TreeNode \(" \operatorname{ch} 11 d 3:\) . . . }; that simply lists all the pointers to the hundred children is not acceptable.

A node with no children is called a(n) __________.

Suppose the following values are inserted into a binary search tree, in the order given: \\[12,7,9,10,22,24,30,18,3,14,20\\] Draw a diagram of the resulting binary tree.

Give an algorithm for a function Int 1 argest (TreeNode "tree) that takes a pointer to a root of a binary search tree as parameter and returns the largest value stored in the tree.

A(n) __________ is an entire branch of the tree, from one particular node down.
