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.

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

a) A
b) E
c) F
d) Both E and F

View Answer

Answer: d

a) 1
b) 2
c) 3
d) 4

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

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

Which of the following is the implementation of the ternary tree?
a) AVL Tree
b) Ternary Heap
c) Hash Table
d) Dictionary

View Answer

Answer: b
Explanation: Ternary tree is used to implement ternary search tree and ternary heap. While AVL Tree, hash Table, dictionary are different types of Data Structures.
