See how we teach edge case mastery
Learn to identify potential edge cases before they cause bugs in your code. Our methodology helps you develop the intuition to spot those unusual scenarios that might break your solution.
Each edge case is explained in detail with both video and text walkthroughs, helping you understand why they occur and how to handle them effectively in your code.
Our step-by-step tutorials highlight edge cases in real time as you code, showing you exactly where your solution might break and guiding you to make it more robust.
We've cataloged common edge case patterns across different problem types, helping you develop the skills needed to anticipate edge cases in any new challenge.
Learn edge case handling in JavaScript, Python, Java, or C++. Our solutions demonstrate language-specific considerations for managing unusual inputs and boundary conditions.
Demonstrate your thorough understanding of programming concepts with our certification that shows employers you can write robust, production‐ready code that handles all scenarios.
Struggle to identify potential edge cases during interviews, often discovering them only after your solution fails
Feel confident with your main algorithm but get tripped up by unexpected inputs or boundary conditions
Want to demonstrate deeper understanding to interviewers by proactively addressing edge cases before being prompted
Need to write more robust, production‐ready code that handles all possible scenarios, not just the happy path
Want to develop the intuition to anticipate edge cases – a skill that separates junior developers from senior engineers
“After going through all the lessons, I gained the necessary skills to perform well at my on-sites. I crushed even the DP problems, which were my biggest fear. And thanks to that I landed offers from Microsoft and Uber. Thank you AlgoCademy!”
Cristina Radulescu
Senior Software Engineer at Uber
“AlgoCademy really helped me improve my problem solving skills and write incredibly clean code. I was worried it wouldn’t be done in time for my coding interviews, but the way the curriculum is structured made me progress very quickly. Thanks for your work!”
Connor Holland
Software Engineer at Vanguard
“Wow. I’ve been using AlgoCademy for a while and now I can finally solve coding questions on my own. This gave me the confidence I needed for my interviews, and guess what? I landed the offer at Samsung! You guys truly kick ass. High fives!”
