Questions and Answers

What is the definition of a tree in the context of data structures?

A tree is a finite set of one or more nodes such that it has a specially designated root node and the remaining nodes are partitioned into disjoint sets, each of which is a tree.

Define the parent node in the context of a tree data structure.

The parent node is the node which is a predecessor of a given node in a tree.

What is the root node of a tree?

The root node is the topmost node of a tree or the node which does not have any parent node.

Explain the concept of child nodes in the context of a tree data structure.

A child node is the immediate successor of a given node in a tree structure. Signup and view all the answers

What are subtrees in the context of a tree data structure?

Subtrees are the disjoint sets into which the remaining nodes, apart from the root, are partitioned in a tree, and each of these sets is itself a tree. Signup and view all the answers
