Linear vs Non-Linear Data Structures

Questions and Answers

What defines a linear data structure?

Elements are stored sequentially. (correct)

Elements can only be accessed in random order.

Elements have a hierarchical relationship.

Elements are connected to multiple elements.

Array

Tree (correct)

Queue

Stack

Why are linear data structures easier to implement compared to non-linear data structures?

They can connect to more than two elements.

Elements are organized in memory sequentially. (correct)

They allow for greater complexity in connections.

They require less memory.

Study Notes

Data Structure Overview

Data structures store and organize data efficiently for use in algorithms.
Classified into two main categories: Linear and Non-Linear.

Linear Data Structure

Elements are stored sequentially, with connections to the previous and next elements.
Traversal and access of elements occur in a single run.
Easier implementation due to sequential organization in memory.
Single element access at a time, with types including:
- Array: Fixed-size collection of elements.
- Queue: FIFO (First In First Out) structure for managing data.
- Stack: LIFO (Last In First Out) structure for data management.
- Linked List: A series of nodes where each node points to the next.

Non-Linear Data Structure

Elements are arranged non-sequentially and cannot be traversed in a single run.
Each element can connect to more than two other elements.
Types include:
- Trees: Hierarchical structure with parent-child relationships.
  - Example: Organizational chart - a manager (parent) linked to officers and clerks (children).
- Graphs: Comprised of vertices and edges.
  - Used to connect data elements (vertices) through relationships (edges).
  - Applicable in real-world scenarios like networks (telephone, circuit, social platforms).

Comparison: Linear vs Non-Linear

Linear structures have sequential connections; non-linear structures have multiple connections.
Linear structures allow single traversal; non-linear structures require multi-directional access.
