,1: Introduction to Data Structures**
- Overview of data structures
An overview of data structures provides a high-level
understanding of what data structures are, why they are important,
and the main categories of data structures commonly used in
computer science and programming. Here's a brief overview:
**What Are Data Structures?**
Data structures are a fundamental concept in computer science and
software development. They are a way of organizing and storing data
to perform various operations efficiently. Data structures define the
format, organization, and access methods for data elements.
**Why Are Data Structures Important?**
Data structures are crucial because they enable programmers to:
1. **Organize Data:** Data structures help in organizing and
managing data in a structured manner, making it easier to work with
large datasets.
2. **Efficient Operations:** Different data structures are designed for
specific operations (e.g., searching, sorting, insertion, deletion) and
can significantly improve the efficiency of those operations.
, 3. **Memory Management:** Efficient use of memory is critical in
programming. Data structures help optimize memory usage.
4. **Abstraction:** They provide a level of abstraction, allowing
programmers to focus on solving problems without worrying about
low-level details.
**Common Categories of Data Structures:**
Data structures can be categorized into various types based on their
properties and usage. Some common categories include:
1. **Arrays:** Arrays are a collection of elements, each identified by
an index or a key. They have a fixed size and are suitable for random
access.
2. **Linked Lists:** Linked lists are composed of nodes, each
containing data and a reference to the next node. They are used
when dynamic resizing is needed.
3. **Stacks:** Stacks follow the Last-In-First-Out (LIFO) principle.
Elements are added and removed from the same end, like a stack of
plates.
