CQH102: Introduction to Data Structures

Why Data Structures Matter

Data structures are the foundation of efficient programming. They determine how we store, access, and manipulate data—impacting everything from simple applications to complex systems. Without the right data structure, even the best algorithms can become slow and inefficient.

CQH102 will guide you through the core data structures used in programming, showing how they interact with the algorithms covered in CQH103. By mastering these concepts, you’ll be able to choose the right structure for any problem and optimize your code for performance.

What We’ll Cover

Throughout this course, we’ll explore:

Arrays and Linked Lists – The fundamental ways to organize sequential data.
Stacks and Queues – Managing ordered data for efficient processing.
Hash Tables – Super-fast data lookup using key-value pairs.
Trees and Graphs – Representing hierarchical and networked data.
Heaps and Tries – Advanced structures for prioritization and searching.

CQH102 & CQH103: A Powerful Pair

Algorithms and data structures work hand in hand. A well-designed algorithm is only as good as the structure that supports it. That’s why CQH102 (Data Structures) and CQH103 (Algorithms) run side by side—so you can see the real-world impact of these concepts together.

Get Ready to Build Smarter Programs

By the end of this course, you’ll not only understand data structures, but also know when and why to use them. Whether you’re building software, designing games, or solving real-world problems, this knowledge will be invaluable.
