Which Is Non Linear Data Structure McQ?

A data structure is a way of organizing and storing data in a computer’s memory. There are two types of data structures: linear and non-linear. In this article, we will focus on non-linear data structures and explore some multiple-choice questions (MCQs) to test your understanding.

Question 1:

What is a non-linear data structure?

• a) A data structure where elements are arranged in a sequential manner.
• b) A data structure where elements are connected in a hierarchical manner.
• c) A data structure where elements are arranged randomly.
• d) A data structure that cannot store multiple types of elements.

The correct answer is b) A data structure where elements are connected in a hierarchical manner. Non-linear data structures allow more complex relationships between elements compared to linear data structures, which have a simple sequential arrangement.

Question 2:

Which of the following is an example of a non-linear data structure?

• a) Array
• c) Stack
• d) Tree

The correct answer is d) Tree. Trees are widely used as non-linear data structures to represent hierarchical relationships between elements. They consist of nodes connected by edges, with one node being the root and others forming parent-child relationships.

Question 3:

What is the time complexity for searching an element in a binary search tree?

• a) O(log n)
• b) O(n)
• c) O(n log n)
• d) O(1)

The correct answer is a) O(log n). Binary search trees provide efficient searching operations, where the time complexity is logarithmic with respect to the number of elements in the tree. This makes them suitable for applications that require fast searching.

Question 4:

Which non-linear data structure is used for implementing a priority queue?

• a) Stack
• b) Queue
• c) Heap
• d) Graph
