OUR MISSION

Learn to code at your own pace

We’ve designed AlgoCademy with people who don’t have a lot of experience with algorithms and data structures in mind. We want to teach people who are looking for the increased satisfaction and income that a programming job can provide.

Is AlgoCademy right for you? Simply put, we're for you if...

You’re trying to prepare for coding interviews but don’t know where to start, or how to come up with an efficient study plan

You’ve spent countless hours trying to solve coding questions online, but you’ve grown frustrated, feeling like you can’t build a solution from scratch

Even if you are able to devise an approach that solves your coding challenge, you aren’t able to write quality code which passes the coding interview

You’re looking to gain the speed and accuracy needed to solve a coding challenge that may get asked of you in interviews

You start to experience sensory overload thinking about all of the information out there about preparing for coding interviews, and you find yourself stuck for days, googling information on various topics, messing up your consistency and flow

“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!”

Frequently Asked Questions

Have questions about code duplication? We’re here to help.

Is code duplication always bad?

No, code duplication isn't always bad. While it's generally advisable to avoid unnecessary repetition, there are scenarios where duplicating code can improve readability, maintainability, or performance. The key is to know when duplication is warranted and when it should be refactored.

When is it acceptable to duplicate code?

Duplication can be acceptable when the code is stable, rarely needs changes, or when an abstraction would complicate rather than clarify. Evaluate the trade-offs before deciding to refactor.

How can I refactor duplicated code for better maintainability?

Refactoring involves extracting common functionality into functions or modules and parameterizing similar code blocks. This reduces redundancy while preserving clarity.

What are the benefits of thoughtful code duplication?

Thoughtful duplication can simplify debugging and improve code clarity, especially when creating an abstraction might lead to over-engineering.

How do I decide between refactoring and leaving duplication?

Consider factors like code stability, frequency of changes, and the cost of abstraction. Weigh these elements to decide whether to refactor or leave the duplication.

Where can I learn more about effective refactoring techniques?

Explore our interactive lessons and video tutorials for in-depth guidance on refactoring methods and best practices to manage duplicated code.
