What is LeetCode?
LeetCode is a comprehensive platform designed for both experienced programmers and aspiring coders. It aims to enhance coding skills and equip individuals for technical interviews by providing various carefully curated challenges. From beginner-friendly to highly challenging, these exercises encompass diverse topics, including algorithms, data structures, and system design.
Beyond this, LeetCode is also a business where companies scout and hire software developers. This makes LeetCode popular among global tech companies such as Uber, Stripe, and Apple, which use the platform’s interview questions to hire software developers directly or through hiring agencies.
What is AlgoExpert?
AlgoExpert is an online platform serving as a valuable resource for software engineers to master algorithms and data structures.
With a wide array of offerings, such as interactive coding challenges, enlightening video tutorials, and an engaging community forum, AlgoExpert caters to the needs of seasoned professionals and aspiring engineers seeking to elevate their skills and interview preparation.
AlgoExpert offers several comprehensive products for programmers, all designed to help you ace interviews in the following areas:
- AlgoExpert - general coding interviews
- FrontendExpert - for frontend development interviews
- ProgrammingExpert - learn how to code
- SystemsExpert - for system design interviews
- MLExpert - for machine learning interviews
- Blockchain - for learning blockchain development
Next, let's compare sides to help you understand each platform’s unique features.
AlgoExpert covers nine programming languages:
AlgoExpert also offers a variety of courses and tutorials on these languages, so you can learn the basics or brush up on your skills.
With LeetCode, you can experiment with up to 14 programming languages. These include:
Other languages include Scala, Swift, TypeScript, C#, Bash, Rust, and PHP.
In addition to providing code samples for each language, LeetCode also offers tutorials and articles to help you understand the basics. You can also find helpful hints and tips from experienced coders to grasp the language better and learn more quickly.
If you’re interested in working with competitive programming, LeetCode is the perfect choice. It offers various coding challenges ranging from easy to difficult levels.
LeetCode confidently takes the crown as the ultimate winner. With an impressive array of 14 programming languages, it undoubtedly holds a distinct advantage over AlgoExpert, providing ample opportunities for exploration and growth.
AlgoExpert features 195 interview questions in at least 15 categories and four difficulty levels.
Currently, AlgoExpert features:
- 31 easy interview questions
- 73 medium-difficulty interview questions
- 54 hard interview questions
- 37 very hard interview questions.
You can distinguish the various levels by their color code — green, blue, red, and black.
The categories include:
- Dynamic programming
- Binary trees
- Famous algorithms
- Greedy algorithms
- …and a few more.
Every interview question has several solutions, video explanations, output, and test cases.
LeetCode offers 2500+ interview questions spanning up to 70 programming categories.
The most popular category is Array, with over 1400 questions. Next is String with 624, and then Hash Table with 487. LeetCode updates the questions frequently, where new ones are added and others removed. This means the count is not static.
What makes LeetCode shine over AlgoExpert is that you can sort questions by company. They feature tons of questions from top tech companies like Apple, Uber, Microsoft, and Adobe.
Again, LeetCode wins in this category — with over 2500 interview questions against AlgoExpert, which has 195.
AlgoExpert provides 100+ hours of video content. The videos include explanations of each interview question on the platform.
With AlgoExpert, you get two types of video explanations:
- Conceptual overview: The instructor explains the programming concept, including how to approach, analyze, and optimize the solution.
- Code walkthrough: The second part covers the code implementation from start to end.
Note: While AlgoExperts’ videos provide a step-by-step process, they are only available in Python.
Nonetheless, the videos are of excellent quality, and the audio is generally great.
The LeetCode explore section offers users access to video explanations under two categories:
- Learn - features videos of 22 programming concepts.
- Interview - features videos of 18 interview concepts, including interviews from companies like Microsoft, Facebook, and Uber, among others.
In the Learn Section, each concept gives you 20 hours of video — meaning you get at least 440 hours of video.
However, some videos in the learn section include parts of LeetCode courses. Some of them have independent and relatively higher costs. Other video materials also require you to pay for LeetCodes’ premium subscription.
Once again, LeetCode wins in this category. However, AlgoExpert’s video structure is also ideal for beginners as it offers a more structured approach to tackling questions.
AlgoExpert premium subscription starts at $99 per year. Nevertheless, this is merely one of the numerous pricing plans available should you decide to upgrade to a premium account.
LeetCode has a more straightforward pricing tier with two pricing plans. These include:
- Monthly Plan: $39/month
- Yearly Plan: $159/year
Concerning affordability, AlgoExpert wins — it’s the cheaper alternative. However, it is important to note that subscriptions for both websites come with additional features of their own, making the choice of one over another ultimately subjective.
LeetCode vs AlgoExpert: Pros And Cons
- More focused on data structures and algorithms
- Tailored packages on different tech areas
- More detailed video explanations
- Better community and support
- More affordable
- Walk-through videos are only filmed in Python
- Fewer interview questions
- Supports multiple programming languages
- A high number of interview questions
- More interactive features such as leaderboards and discussions forum
- Some video explanation materials are independent and more expensive
- Quality–wise, video explanations aren’t in-depth
LeetCode vs AlgoExpert: Which is Ideal for a Frontend Developer?
As a frontend developer, you may wonder which platform is ideal for your interview questions. We assessed a few factors and determined that AlgoExpert is a better platform for frontend development than LeetCode for the following reasons:
- AlgoExpert's problems are more realistic and representative of the problems that frontend developers face in the real world. LeetCode's problems are often more theoretical and abstract, which can be less helpful for frontend developers.
Throughout this analysis of AlgoExpert and LeetCode, we delved into two remarkable platforms for coding interview preparation.
AlgoExpert caters to learners with its curated set of 190+ hand-picked questions and expert video explanations. In contrast, LeetCode offers a more extensive library of 2500+ coding problems and supports a wide range of programming languages.
That said, due to its cheap pricing, AlgoExpert stands out as an ideal platform for frontend developers looking to practice interview questions or users looking for a cheaper alternative. However, if you want to prepare for general software development, we recommend choosing LeetCode as it has a large pool of resources and materials.
As you embark on your coding journey, consider your preferences, learning style, and goals to select the platform that aligns best with your needs.
