Ternary Tree Multiple Choice MCQ – 2
1 - Question
How many extra nodes are there in Full ternary tree than a complete ternary tree?
a) 1
b) 2
c) 3
d) Both have same number of nodes
View Answer
Answer: d
Explanation: Every Full ternary tree is also a complete ternary tree. Therefore, both have same number of nodes.
2 - Question
Is Node A sibling of Node D in the given ternary tree?
a) True
b) False
View Answer
Answer: b
Explanation: Node B, Node C are the siblings of Node D while Node A is the parent node of Node D.
3 - Question
What is the size of the given ternary tree?
a) 3
b) 2
c) 6
d) 4
View Answer
Answer: c
Explanation: Size of the ternary tree is defined as the total number of nodes present in the tree. Since there are total of 6 nodes in the ternary tree. So the size of the ternary tree is 6.
4 - Question
Who is the ancestor of Node G?
a) C
b) F
c) H
d) A
View Answer
Answer: a
Explanation: Ancestor node is a node that comes in between the path from the node to the root. Since Node C comes between node G and root, so Node C is called the ancestor node.
5 - Question
Who is descendant of Node B?
a) A
b) E
c) F
d) Both E and F
View Answer
Answer: d
Explanation: Descendant node is a node which has a direct path from ancestor node. Since both E and F are connected to B, so Node E and Node F are the descendants of Node B.
6 - Question
What is the size of Node A?
a) 1
b) 2
c) 3
d) 4
View Answer
Answer: d
Explanation: Size of node is defined as the total number of descendants of that node including itself. So, size of Node A is 4.
7 - Question
Can leaf node be called child node in a ternary tree?
a) True
b) False
View Answer
Answer: a
Explanation: Leaf node is a node that has no child. Since Leaf node will always be the node on the last level of ternary tree, so it can be called child node of given parent node in ternary tree.
8 - Question
Can child node be always called Leaf node in the ternary tree?
a) True
b) False
View Answer
Answer: b
Explanation: Leaf node is any node that does not contain any children. Child node may or may not contain more nodes. Child node will only be called leaf Node if the node has no child node.
9 - Question
