CQH102 – Data Structures
Welcome to CQH102: Data Structures, the second course in our CodeQuestHub series. In this course, you’ll explore the building blocks that power how data is stored, accessed, and manipulated in programs.
If you’ve completed CQH101 – Fundamentals of Programming, you’re ready to take the next step into the world of arrays, stacks, trees, graphs, and more.
Why Learn Data Structures?
Data structures are the backbone of computer science. Whether you’re building a game, a web app, or analyzing large data sets, choosing the right structure can make your program faster, smaller, and smarter.
With each lesson, you’ll learn:
- What the data structure is
- Why and when it’s used
- How to implement it
- How it performs (time and memory complexity)
What You’ll Learn
📦 Arrays and Lists – The foundation of sequential data.
📚 Stacks and Queues – First-in-first-out vs last-in-first-out structures.
🌳 Trees – Hierarchical structures used in everything from file systems to games.
🌐 Graphs – Representing networks, maps, and connections.
🎯 Hash Tables – Fast lookups with clever key management.
⚖️ Performance Tradeoffs – Learn how complexity impacts your program’s efficiency.
Each post includes clear explanations, code examples, and visualizations to help you understand how each structure works and why it matters.
Who Is This Course For?
- Students who completed CQH101 or have basic programming experience.
- Self-taught coders looking to deepen their understanding of how programs work behind the scenes.
