Crash Course: Beginner Data Structures And Algorithms Concepts
Tired of the frustrating LeetCode grind?
The reason people struggle with learning data structures and algorithms (DSA) is that they go about it in the completely wrong way. They jump straight into trying to solve problems without the proper prerequisite knowledge. This is why studying DSA feels like a slow "grind" for many.
If you are going to land your dream job, you are going to need to build your knowledge in a way where you can apply your skills to new problems, when it matters most, on a technical interview.
In this crash course we'll build up your DSA knowledge gradually so you never miss a step. We'll cover the key patterns and concepts that you can leverage to solve the most common interview problems. By the end of this course, you will be able to:
- Solve interview problems about hash-maps, linked lists, binary trees, graphs, and dynamic programming
- Analyze algorithms using Big-O notation so an optimal implementation is achieved
- Visualize and understand core algorithm concepts so you can apply them to solve new problems
This course is designed for beginners, so you don’t need any DSA knowledge to begin. We will start at the fundamentals and increase the difficulty slowly over time; this is the key to truly mastering the concepts.
Once you complete this course, you’ll have the skills you need ace your technical interviews and land your dream job.
If you need additional support taking those skills and actually applying them, take Alvin's complete data structures and algorithms course on Structy. You can try out the concepts yourself in their interactive code editor and learn advanced DSA patterns like stack exhaustive recursion.

Hey Programmers!
I'm Alvin. I'm a software engineer with a serious passion for teaching. I'm a former Google Software Engineer. I'm also a former Lead Curriculum Developer of a top coding bootcamp. I'm a Featured Instructor on the freeCodeCamp YouTube channel, where my lectures have accumulated over 6 million views.
I have spent the better part of the last decade teaching students the skills needed to be a great developer and land their dream job.
Through years of experience leading in the classroom, working with students one-on-one, and in front of the video camera, I've developed a teaching style that I'm excited to share with you. I believe that gradual progression is the key to building robust knowledge that you'll be able to apply in your interviews and on the job. We'll go slow so that you don't miss a step. With my system, you'll enter the course as a beginner, but leave with the skills to land your dream job.
Let's learn together.
Unique and fabulous! Those are the words that come into mind when thinking about Structy. No other resource matches what Alvin developed. I was struggling heavily with Leetcode and other resources before finding Structy. If you have time only for one resource before your interview, let it be Structy.
The way the lecturer explains is the gold standard of how one should speak during the interview. The animations on videos are excellent and not some lazy scribbles on online whiteboards. Thanks, Alvin!
Structy was the foundation of my interview preparation. The clear approach and walkthrough videos make it easy to learn essential topics necessary for big-tech interviews. I had a lot of data structure & algorithm gaps to fill in my knowledge. Alvin seamlessly filled those gaps.
Structy was a total game changer for me. The curriculum helped me build the knowledge base required to successfully navigate the big tech interview process, which led to two offers at FAANG companies and my dream job.
Solving raw data structures and algorithms problems isn't what most software engineers do in their day-to-jobs but completing Structy has given me the necessary skills to excel at my role at Justworks. Alvin's approach on teaching along with his thoughtfully produced videos make Structy well worth it!
I'm not exaggerating when I say I probably wouldn't have passed my technical onsite interview if it weren't for Structy. Before Structy, I would frantically study random algorithms and feel lost. I highly recommend it for people who don't know where to start when preparing for interviews.
Alvin's explanations are very clear and nice. Really appreciate that.
Alvin doesn't drill you on several hundred problems you MIGHT see, instead it focuses on quality and succeeds, teaching you problem solving strategies you can easily adapt to many other situations.
After sampling competing products, I can confidently say that Structy is the best bang for your buck. Alvin's unique teaching style coupled with the purposefully chosen questions hammers in the concepts that you need to know with spaced repetition.
