Module 13 — Computer Science Fundamentals

Why CS Fundamentals Matter​

You can build CRUD apps without knowing Big-O notation. But to write code that scales, pass technical interviews at top companies, and understand why certain patterns are better than others, you need CS fundamentals.

Learning Objectives​

  • Analyze algorithm efficiency with Big-O notation
  • Understand common data structures and when to use each
  • Implement sorting algorithms and understand their trade-offs
  • Use recursion to solve tree/graph problems
  • Recognize and write efficient algorithms

Module Lessons​

  1. Big-O Notation
  2. Data Structures
  3. Sorting Algorithms
  4. Recursion

Challenge​

Solve 5 LeetCode-style problems, each targeting a specific concept from this module, with documented time and space complexity analysis.
