The 90-Day Algo Marathon

Stop Grinding. Start Bingeing.

The 90-Day Algo Marathon Cover

Your journey from logic-blind to logic-master.

Most people fail LeetCode because they try to memorize solutions. We believe in mastering the visual patterns and the underlying logic through stories that stick.

📖 The Story Behind the Book

This book didn't start in a publishing house; it started in the hands of thousands of mobile users.

When we launched our LeetCode Learn mobile app, we expected users to focus on the raw practice problems. However, something unexpected happened. We noticed an overwhelming amount of positive feedback—not for the code runner, but for the short handbooks and illustrated stories we added as "filler" content.

Users loved the quirky analogies, the visual breakdowns of complex graphs, and the way we humanized the "Two Sum" or "Dijkstra" algorithms. They told us: "This is how I finally understood it."

That was our "Aha!" moment. We realized there was a massive gap in technical education: The Soul of Logic.


📺 Stop Grinding. Start Bingeing.

We decided to try something radical. What if we treated algorithms not as math equations, but as plot twists?

In this book, you won’t just be learning Python. You will be joining Eden, a sharp, self-taught coder from the "Dumpster District" (the legacy code slums), as she bluffs her way into the most prestigious estate in the Silicon Forest.

She isn’t coding on a laptop. She is physically organizing a chaotic mansion. She has 90 days to prove she belongs, or she gets kicked out by Max (the brilliant but eccentric Senior Architect) and Sasha (the ruthless Head of HR who wants her to fail).
