10 Questions
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.
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.
What is the hierarchical structure of a tree in terms of data storage?
The data in a tree are arranged on multiple levels in a non-sequential manner, forming a hierarchical structure.
How is a tree defined in the context of data structures?
A tree is a finite set of one or more nodes with a specially designated root node, and the remaining nodes are partitioned into disjoint subtrees.
What is the parent node in the context of a tree data structure?
The node which is a predecessor of a node is called the parent node of that node.
Explain the concept of a root node in a tree data structure.
The topmost node of a tree, or the node which does not have any parent node, is called the root node.
What is the requirement for a nonempty tree in terms of the number of root nodes?
A nonempty tree must contain exactly one root node.
