Data structures are the basic components of software development, and algorithms are effective methods for solving certain programming problems. Learning data structures and algorithms has always been one of the most important concepts to learn as a software developer.
To crack the coding, you need to conduct interviews with aspiring companies. will be based on products such as For FAANG companies, it is inevitable to learn and consolidate the fundamentals of data structures and algorithms.
But the best part is learning the data structures and algorithms are not needed to crack programming interviews, this knowledge is never obsolete and the concepts you will learn will help you grow as a developer in the long term.
In this article, I would like to present my three most important resources for learning data structures and algorithms.
1. W3Schools - Blog about data structures and algorithms
First, the series of posts from W3Schools, a free and popular site for learning concepts.
The algorithms are mainly taught in C++, so I recommend it to anyone who knows this language at an intermediate to advanced level.
Since it is a blog. It's completely self-contained and you can come back whenever you need a quick refresher. If you are new to data structures and algorithms, this may not be a good place to start as I find the articles to be more of a summary/review note than a detailed explanation.
I like that the articles are easy to understand and well organized. Sometimes I also find that text formatting is quicker to understand and learn.
2. freeCodeCamp: Basic to Advanced Data Structures
If you prefer to learn without the stress of submitting assignments and taking tests, freeCodeCamp offers this 8-hour video where you can watch and learn basic to advanced data structures.
You'll learn about stacks, linked lists, queues, hash tables, and more. The course is taught in Java, so you will learn how to implement these data structures in Java code. Intermediate knowledge of Java is required.
Although this course focuses primarily on data structures, you will become familiar with common algorithms such as Kruskal or hashing algorithms. The course is easy to understand for both beginners and advanced students.
Since this is a video, it is completely free and can be done at your own pace and you can review the concepts at any time. So if you're looking for a more detailed review on the topic of lack of time, this might be the best option.
If you're interested, don't. Do not hesitate to contact us visit. You can find the link here.
However, remember that watching an instructional video is a passive way of learning. So for it to work you still need to put the concepts into practice. You learn by programming.
3. GeeksforGeeks: Data Structures and Algorithms
Finally, we have GeeksforGeeks Data Structures and Algorithms. If your goal is to join a large tech company, this option is recommended for you.
This course is taught by the most credible in C++ and Java. and eminent educators in India along with a team of experts. Plus, your program is regularly updated to reflect new industry standards. Even if you are a beginner, you will have no problem following the course as the course starts with the basics.
For example, I find the type and way L The instructor explained the asymptotic analysis with examples and clear step-by-step explanations, very easy to understand! I also like the fact that it's not just about watching videos, but also lots of hands-on exercises from big tech companies like Google, Microsoft, Adobe, etc. and helps you become an effective developer. There are additional articles to read and assessment tests to accompany learning and practice in learning projects based on real-world applications.
They also have forums where you can publish. ask questions. If you have any questions or need help registering for the course, you can access 24/7 “Question Support”, which is personalized and can be used to resolve all questions and problems regarding any topic via chat, telephone and even video calls.
Another advantage of this course is unlimited access and a course completion certificate accepted and recognized by the leading technology giants in the industry.
What you will learn:
- Master DSA from basic to advanced level
- How to solve problems which are asked in product-based companies
- Solve problems in contests similar to coding round for SDE role
- How to become a strong and efficient developer
- Practice DSA concepts with a real time project (Sudoku Solver)
If this sounds like the right course for you, I have collaborated with GeeksforGeeks so you can get a 10% discount off any course!
A perfect course for everyone may not exist, but there is a perfect course for you. I hope this list helps you narrow down some platforms where you can learn and get started building your foundation in programming.
Thanks for reading! I wish you all the best in your learning journey. If you know any other good courses you have taken, feel free to let me know in the comments below. Cheers!
