Watch a sample optimization lesson
Apply time complexity analysis to real coding problems with our interactive practice exercises designed to sharpen your optimization skills.
Watch our instructors break down the step-by-step process of analyzing and optimizing algorithm runtime, with clear explanations of Big O notation and complexity tradeoffs.
Utilize interactive tools that help you visualize algorithm performance across different input sizes, making it easier to spot bottlenecks.
Learn specific strategies to optimize algorithms—from converting O(n²) solutions to efficient O(n) or O(log n) approaches—with practical examples.
Optimize your solutions in your preferred language—be it Python, JavaScript, Java, or C++—with examples tailored to each language’s strengths.
Compare your optimized solutions against benchmark metrics to ensure your code meets industry standards for efficiency.
You can solve coding problems but struggle to optimize them for efficient time complexity.
Your correct solutions are often too slow, costing you interview opportunities.
You understand Big O notation in theory but find it challenging to apply in practice.
You want to shift from brute force approaches to efficient, scalable algorithms.
You need structured, hands-on practice with instant feedback to build your optimization intuition.
"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!"
Ankit Kumar
Software Engineer at Samsung
