Which of the following is not an example of linear data structure?a.Queueb.Stackc.Linked Listd.Graph

Break Down the Problem

1. Identify the given options: Queue, Stack, Linked List, and Graph.
2. Classify each option based on its characteristics as a linear or non-linear data structure.

Relevant Concepts

1. Linear Data Structures: These data structures arrange data in a sequential manner where each element is connected to its previous and next element.

   • Examples: Arrays, Linked Lists, Stacks, Queues.

2. Non-Linear Data Structures: These data structures do not organize data in a sequential manner and can have hierarchical structures.

   • Examples: Trees, Graphs.

Analysis and Detail

1. Queue: A linear data structure that follows the FIFO (First In First Out) principle.

2. Stack: A linear data structure that follows the LIFO (Last In First Out) principle.

3. Linked List: A linear data structure where each element points to the next, forming a sequence.

4. Graph: A non-linear data structure that consists of nodes (or vertices) and edges, which can connect any node to any other node. This structure does not maintain a sequential organization as seen in linear data structures.

Verify and Summarize

After analyzing all options, we observe that Queue, Stack, and Linked List are all examples of linear data structures, while Graph is not.

Final Answer

d. Graph is not an example of a linear data structure.
