Data Structures & Algorithms Multiple Choice Questions on “Ternary Heap – 2”.
1. What is the time complexity for inserting a new item in a ternary heap of n elements?
a) O (log n/ log 3)
b) O (n!)
c) O (n)
d) O (1)
Answer: a
Clarification: In order to insert a new item in a ternary heap data structure having n elements, the heap has great efficiency for inserting them. So the time complexity for worst case is found to be O (log n/ log 3).
2. Is decrease priority operation performed more quickly in a ternary heap with respect to the binary heap.
a) True
b) False
Answer: a
Clarification: Ternary heap is a type of data structure in the field of computer science. It is a part of the Heap data structure family. Due to the swapping process, the decrease priority operation performs more quickly in a ternary heap.
3. What is the time complexity for decreasing priority of key in a minimum ternary heap of n elements?
a) O (log n/ log 3)
b) O (n!)
c) O (n)
d) O (1)
Answer: a
Clarification: In order to decrease the priority of an item in a ternary heap data structure having n elements, the heap has great efficiency for decreasing them. So the time complexity for worst case is found to be O (log n/ log 3). This is due to the upwards swapping process.
4. What is the time complexity for increasing priority of key in a maximum ternary heap of n elements?
a) O (log n/ log 3)
b) O (n!)
c) O (n)
d) O (1)
Answer: a
Clarification: In order to increase the priority of an item in a ternary heap data structure having n elements, it performs upwards swapping. So the time complexity for worst case is found to be O (log n/ log 3).
5. What is the time complexity for deleting root key in a ternary heap of n elements?
a) O (log n/ log 3)
b) O (3log n/ log 3)
c) O (n)
d) O (1)
Answer: b
Clarification: In order to delete a root key in a ternary heap data structure having n elements, it performs downward swapping. So the time complexity for worst case is found to be O (3log n/ log 3).
6. What is the time complexity for increasing priority of key in a minimum ternary heap of n elements?
a) O (log n/ log 3)
b) O (3log n/ log 3)
c) O (n)
d) O (1)
Answer: b
Clarification: In order to the increasing the priority of key in a minimum ternary heap data structure having n elements, it performs downward swapping. So the time complexity for worst case is found to be O (3log n/ log 3).
7. What is the time complexity for decreasing priority of key in a maximum ternary heap of n elements?
a) O (log n/ log 3)
b) O (3log n/ log 3)
c) O (n)
d) O (1)
Answer: b
Clarification: In order to decrease the priority of key in a maximum ternary heap data structure having n elements, it performs downward swapping. So the time complexity for worst case is found to be O (3log n/ log 3).
8. Do ternary heap have better memory cache behavior than binary heap.
a) True
b) False
Answer: a
Clarification: Ternary heap is a type of data structure in the field of computer science. It is a part of the Heap data structure family. Due to the swapping process, they have better memory cache behavior.
9. What is the time complexity for creating a ternary heap using swapping?
a) O (log n/ log 3)
b) O (n!)
c) O (n)
d) O (1)
Answer: c
Clarification: Ternary Heap can be formed by two swapping operations. Therefore, the time complexity for creating a ternary heap using two swapping operation is found to be O (n).
10. Which of the following is the application of minimum ternary heap?
a) Prim’s Algorithm
b) Euclid’s Algorithm
c) Eight Queen Puzzle
d) Tree
Answer: a
Clarification: When working on the graph in the computer science field, the Prim’s Algorithm for spanning trees uses a minimum ternary heap as there are delete operation equal to a number of edges and decrease priority operation equal to the number of vertices associated with the graph.
