image — Grokking the Coding Interview: Patterns for Coding Questions

Hello guys, How are you doing? It’s been a long time since I wrote anything here, so here I am, sharing with you a couple of nice articles you can read this week on Data Structure and Algorithms. Along the way, I will also share some interesting books and courses for those who want to deep dive into this important topic.

So, without wasting any more of your time, here is my list of 10 Data Structure and Algorithms Articles Programmers can read this week:

14 Patterns to Ace Any Coding Interview Question by Fahim ul Haq

This is my favorite article of this week, I am a big fan of Fahim ul Haq’s writing and love his articles so you may consider a bit partisan but you will agree with me once you read this article.

This article will teach you some of the common techniques to solve coding problems in interviews like the two-pointer approach, recursion, slow-fast pointer approach, sliding window, dynamic programming, and much more.

Actually, this article is just an introduction to their course — Grokking the Coding Interview: Patterns for Coding Questions, so if you feel to deep dive on these patterns you can also check out this course.

10 (Free) Data Structure and Algorithm Courses Junior Developers Should Explore by javinpaul

This is my article on Hackernoon and I have shared a bunch of helpful free courses to learn data structure and algorithms. These courses will not only teach you basic data structures like an array, linked list, binary tree, and hashtable but also advanced data structures like TRIE, Self-balanced trees like AVL and Red-Black tree, Graph, etc. If you like learning from free resources then you will enjoy these collections of courses.

Solving the classic Two-Sum and Three-Sum Problem in JavaScript by Rohan Paul

I have been learning JavaScript and what is better to keep it improving than solving coding problems in the language. This will help you to not only learn syntax but also how to build logic using the language. If you love solving coding problems you will enjoy this article.

Rohan, chat with me if you love to join our publication? I love your article and would be glad to host you here.

Btw, you should have basic knowledge of Data Structure and Algorithms before you go for coding interviews. If you are new to the Data structure and Algorithms, here are a few courses to refresh your knowledge depending upon which programming language suits you best, Like:

  1. Data Structures and Algorithms: Deep Dive Using Java for Java developers
  2. Algorithms and Data Structures in Python for those who love Python
  3. JavaScript Algorithms and Data Structures Masterclass by Colt Steele for JavaScript programmers
  4. Mastering Data Structures & Algorithms using C and C++ for those who are good at C/C++

A graphical introduction to dynamic programming by Avik Das

Dynamic programming is an interesting concept and very useful too, particularly if you are preparing for coding interviews. This article provides an introduction of Dynamic programming with a different angle and using a different way, this might help you to learn it better.

If you want to learn more about Dynamic programming, here are a couple of more resources to learn Dynamic Programming better:

  1. Intro To Dynamic Programming — Coding Interview Preparation
  2. Dynamic Programming — I

Data Structures 101: Graphs — A Visual Introduction for Beginners by Estefania Cassingena Navone

The graph is one of the most important data structures but is often overlooked by beginners thinking that it's too complex to understand. If you are someone who feels Graph is not your cup of tea, this article will probably help you to change your perception. I really enjoyed this article.

Estefania Cassingena Navone, I love your article on freeCodeCamp and would be happy to host you here, chat me if you are interested in publishing on @javarevisited

142 Resources for Mastering Coding Interviews by SeattleDataGuy

A huge collection of resources for preparing for coding interviews, if you like to solve coding problems, you will find a lot of them here. I was a bit sad to not find any of my articles there as some of them like 50+ Algorithms Problems and 20+ String Coding Problems are super useful for programmers preparing for their coding interview, but hey it’s still a very good collection.

How to prepare for competitive programming? by Andrei Margeloiu

This is an old article but I only read it last week. Its the story of how the author won 3 out of 4 Gold medals in the Computing Olympiad and share some very good insights and technique for preparing for competitive programming. I really loved this article and I know you’ll like it too.

Andrei Margeloiu, would you like to join us on Javarevisited? I would be happy to host you here, your stories are worth sharing.

Google Interview Questions Deconstructed: Synonymous Queries by Alex Golec

I love to read anything about Google interview process and whenever I saw stories discussing Google Interview Question, I make sure to read it. If you also share similar liking, then this article is for you.

Just to give you background Alex Golec is Ex-Google and currently working in Reddit NYC, so it’s definitely someone who knows about Google interview process.

Alex Golec, if you are reading this, join us man, I would be happy to add you as a writer for Javarevisited.

Grokking Algorithms — Book Review by javinpaul

Another of mine story about a book which I really love. This is the book I recommend to every beginner and computer science graduate aspiring to learn Algorithms and Data Structure.

The book doesn’t cover all the data structure but whatever it covers, it does it really well. I really loved the pictures, which made me understand the concepts clearly. If you are a visual learner like me then you will enjoy this book.

And if you want to read the book, here is the link — Grokking Algorithms: An Illustrated Guide for Programmers

Btw, if If you need more choices, particularly online courses to deep dive into Data Structure and algorithms for coding interviews and general programming perspective, these are my recommend online courses for Java, Python, and JavaScript developers:

  1. Data Structures and Algorithms: Deep Dive Using Java for Java developers
  2. Algorithms and Data Structures in Python for those who love Python
  3. JavaScript Algorithms and Data Structures Masterclass by Colt Steele for JavaScript programmers

Thanks for reading this article so far guys, Have a nice day and enjoy learning Java and Algorithms.

We are also looking for writers and contributes on Javarevisited, so if you are interested in getting your stories published on Javarevisited, please drop me a note or comment in this article and I’ll add you as a writer.
