Question Discussion & Solution

Answer: Option 3

Concept:

Tree:

• A tree consists of nodes or vertices that store information and often are labeled by a number or a letter.
• A tree consists of directed edges or undirected edges or both.
• The number of subtrees of a node is called its degree.
• A leaf or a terminal node is a node of degree zero
• A node that is not a leaf is called an interior node or an internal node
• The degree of a node is the number of its children. The degree of a tree is the maximum degree of any of its nodes.

Ancestors of a node in a Tree: 

The ancestor nodes of a node are all parent nodes of that particular node.

Explanation: 

Consider the following Binary Tree 

Every node except the root node (A) has ancestors.

Hence in a tree, the only node that has no ancestors is the root node. (only one node possible)

Additional Information

Full Binary Tree: 

A full binary tree is a binary tree in which each node has exactly two or 0 children.

Complete Binary Tree:

A complete binary tree is a binary tree in which

1. except last level tree is completely filled.
2. The last level is filled from left to right.

Perfect Binary Tree: 

A perfect binary tree is a binary tree in which

1. all interior node or internal nodes has 2 children.
2. all leaves are at the same level.

Balanced Binary Tree: 

A Balanced Binary tree is a binary tree in which at any node height of the left subtree and right subtree do not differ by more than 1.

Important Points

1. A tree with n nodes has n - 1 edge.

2.  consider a nonempty binary tree with n0 leaves and n2 nodes of degree two (internal nodes). Then
n0 = n2 + 1
Applications of Trees: 
1. Huffman Coding
2. Evaluation of Arithmetic Expressions using Expression trees
