CS Mastery: Algorithms is a comprehensive and interactive learning app designed to help you deeply understand computer science algorithms — from the fundamentals to advanced concepts — through structured lessons, flashcards, and quizzes. Whether you’re a computer science student, a software engineer preparing for coding interviews, or just passionate about how algorithms shape modern computing, this app will guide you step by step toward true mastery.

Learn Algorithms the Smart Way

Most people struggle with algorithms not because they’re too hard, but because they’re taught in abstract ways that make them difficult to visualize and apply. CS Mastery: Algorithms was created to change that.
The app transforms complex algorithmic ideas into simple, interactive, and digestible lessons. Each topic is carefully broken down to help you not just memorize, but understand the why and how behind every algorithm.

You’ll find detailed explanations, visual aids, and real-world examples for sorting, searching, graph traversal, dynamic programming, recursion, data structures, and more. Every lesson is designed to build on the previous one, ensuring that your understanding grows logically and consistently — just like a solid foundation in computer science should.

Interactive Flashcards

Flashcards are one of the most effective ways to retain knowledge. The app includes a curated set of algorithm flashcards that reinforce your memory with key definitions, time complexities, and common pitfalls. Whether you have 5 minutes or an hour, you can review essential topics anytime, anywhere.

You can also track your progress as you study, mark cards for review, and gradually strengthen your long-term recall. This active learning approach ensures that what you learn sticks — so when you face algorithm challenges in interviews or projects, you’ll remember exactly what to do.

Challenge Yourself with Quizzes

Once you’ve studied a topic, test your understanding through targeted quizzes. Each quiz is designed to evaluate both conceptual understanding and practical thinking.
You’ll face a variety of question types — from multiple choice and code trace problems to scenario-based questions that mirror real interview challenges.

At the end of each quiz, you’ll receive instant feedback and explanations for every answer. You’ll know exactly where you’re strong and where you need to improve, making your learning process both efficient and motivating.

Built by a CS Professional

CS Mastery: Algorithms was built by Stav Bitanski, a Computer Science graduate and experienced software engineer with over 8 years in the cybersecurity industry.
