Master refactoring techniques to manage code duplication effectively and improve your codebase over time.
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!”
“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!”
“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!”

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.
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.
Refactoring involves extracting common functionality into functions or modules and parameterizing similar code blocks. This reduces redundancy while preserving clarity.
Thoughtful duplication can simplify debugging and improve code clarity, especially when creating an abstraction might lead to over-engineering.
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.
