About this course

Algorithms are the foundation of efficient software, transforming slow, brute-force solutions into elegant, high-performing code. Understanding how to search and sort data effectively is a critical step for any aspiring developer. This text-based course guides you from computer science fundamentals to writing and analyzing your own Python implementations. You will develop the analytical mindset needed to choose the right algorithm for any programming challenge. What you'll learn: - Understand the fundamentals of Big O notation and measure code efficiency - Implement essential search algorithms from basic linear search to optimized binary search - Code core sorting algorithms including selection, insertion, merge, and quick sort - Use modern Python features like type hints and dataclasses to organize your data - Compare the time and space complexity of different algorithmic approaches - Practice writing and testing clean, readable Python code through written exercises We begin by breaking down foundational computer science terminology and computational complexity. From there, you will read through step-by-step explanations of each algorithm, complete with Python code examples and structured logic exercises. This course is designed for beginners who know basic Python syntax and want to build a strong foundation in computer science and problem-solving. No advanced math or prior algorithm experience is required. Start reading today to master the core algorithms that power modern software.
