Top 5 Courses to Learn Dynamic Programming for Coding Interviews in 2024 - Best of Lot

Hello guys, If you are looking for a job and giving interviews then you might have noticed that getting a Software development Job is becoming more and more difficult every day. For example, there was a time when you can get a Java developer position by just knowing Core Java concepts like String, Collections, and Multithreading, etc, but, not anymore. There were definitely some questions on Data structure and Algorithms and even on Dynamic Programming at that time as well, but the focus was always on programming language expertise like Java or Python. But, things have completely changed now, and the focus is more and more on the candidate's ability to solve coding problems.

Every company now has a tough coding test, and without passing them, you won't go into the regular round of interviews, where your expertise in a programming language is getting tested.

On these coding tests, some of the hardest problems come from Dynamic Programming, especially for tech giants like Microsoft, Apple, Google, Facebook, and many programmers struggle to solve it.

From my own experience, I can say that understanding the Dynamic Programming algorithm is tough, and you need a lot of practice to get the hang of it. But, just practice won't be enough; you need to learn some tricks to solve those Dynamic Programming problems, and the best way to learn those tricks and approaches is to read good books or join excellent online courses.

A couple of days ago, one of my readers asked me about the Knapsack problem and longest subsequence problem, two of the most popular Dynamic programming problem, and how to solve Dynamic coding problems, as I haven't touched on the topic for a long time, I had to do some research.

As part of my research, I come across some useful resources to learn and master Dynamic programming, which I am going to share with you guys today, along with some useful tips to solve Dynamic programming problems, but before that, let's understand what is Dynamic Programming? and take a look at popular dynamic programming coding problems which can be solved using Dynamic programming.

What is Dynamic Programming (DP)? How to use it?

Dynamic Programming (DP) is an algorithmic technique for solving a bigger and hard problem by breaking it down into simpler sub-problems and utilizing the fact that the optimal solution to the bigger problem depends upon the optimal solution to its smaller sub-problems.

One of the simplest examples of Dynamic Programming problems is the Fibonacci series because it's possible to solve the problem (I mean, Fib(n)) by solving two smaller subproblems (which are Fib(n-1) and Fib(n-2)).

Another popular example of a Dynamic Programming question is the Knapsack problem, which tests your ability to find an optimal solution in a given constraint.

The fact is, Dynamic Programming (DP) problems can be some of the most intimidating in an actual coding interview. Even when it's clear that a problem can be solved using Dynamic Programming (which is also difficult), it can be challenging to even know where to start on the solution. Unless you're trained on the approach to solving Dynamic Programming problems.

Recursion also plays a key role in solving Dynamic programming problems because both solve the problem by dividing a big problem into small problems. Many developers struggle with Recursion and subsequently with Dynamic programming, hence solving some recursion-based coding exercises can also be a good idea to improve your dynamic programming skills. 

Now that we know what is Dynamic Programming and got an idea of what type of problems can be solved using Dynamic Programming let's see some online courses which will train you on Dynamic Programming.

By the way, if you are looking for a complete course which not only covers Dynamic Programming but also Recursion, Backtracking, Data Structures and other competitive programming techniques and also help you to do well on coding interview then this Master the Coding Interview: Data Structures + Algorithms by Andrei Negaoie is one of the best course to join in 2024. It covers everything you need to prepare for coding interviews.

5 Best Dynamic Programming Online Courses to Learn in 2024

These courses have easy-to-understand explanations of some of the famous Dynamic Programming based coding problems, which will help you to learn how to approach and solve them. They also share some tips to identify if a problem can be solved using Dynamic programming.

1. Recursion, Backtracking and Dynamic Programming in Java [Udemy]

This is one of the best online course to learn Dynamic Programming, Recursion, and Backtracking algorithms on Udemy for Java courses. I first come across this course while searching for a solution to a problem that was asked to one of my readers in a Morgan Stanley interview - The Climbing Stairs Problem.

If you are regular in coding interviews, you might have seen this problem before. The problem definition is simple, you can climb either 1 or 2 stairs at a time, how many different ways you can climb N stairs, and the solution presented by Farouk Yasser really blew my mind.

This is not really a funky course with lots of animation to teach you concepts, but the way Holczer Balazs, the instructor of this course explains, the solution makes a difference.

It's also one of the few courses which solve almost all the famous Dynamic programming problems like Climbing Stairs, Cutting Roads, House Robber, the Best time to buy and sell stocks, 0/1 Knapsack problem, Longest Common sub-sequence problem, and Longest common substring problem. If you are looking for a solution to those problems, then this course is for you.

I also suggest you watch a couple of previews of this course, in fact, the climbing stairs problem is solved in the preview itself, and if you are looking for best Dynamic Programming and Recursion course in Java then you can join the course.

2. Grokking Dynamic Programming Patterns for Coding Interviews [DesignGuru]

You may not know already, but DesignGuru, a new interactive online learning platform has some of the best courses for coding interview preparation. 

This course was made from scratch with only one goal in mind - how to approach Dynamic programming problems. It'll equip you with a set of easy-to-understand techniques to handle any DP-based coding problem.

Rather than just having you try to memorize solutions, you'll be walked through five underlying DP patterns that can then be applied to solve 35+ Dynamic Programming problems.

In each pattern, you'll first learn a recursive brute-force solution, which is actually the best way to start solving a DP problem. Once you understood the recursive solution, you'll learn how to apply advanced Dynamic programming techniques of Memoization and Tabulation (using grids).

When it comes to preparing for coding interviews, there is no better place than Educative, they have the best hands-on, interactive coding interview courses. I have already talked about their best course - Grokking the System Design Interview, and this one is another gem.

The course also covers common dynamic programming problems and techniques like a knapsack, sequence alignment, optimal search trees.

And, if you find Coursera specialization and certifications useful, particularly from Google, AWS, and IBM, then I suggest you join the Coursera Plus, a great subscription plan from Coursera which gives you unlimited access to their most popular courses, specialization, professional certificate, and guided projects. It cost around $399/year but it's completely worth your money as you get unlimited certificates.

4. Master the art of Dynamic Programming [Udemy Course]

If you like Udemy courses like me, this is another good course to learn the Dynamic Programming technique. It covers problems like Edit Distance, Regular Expression Matching, Minimum deletion to make a String palindrome, and Longest increasing subsequence.

Most importantly, the way Ajay explains how to approach a Dynamic Programming problem from identification to formulation is great. He also divides the problems into two categories one-dimensional Dynamic Programming problems and Two-dimensional dynamic programming problems.

The course will also teach you Recursion and Backtracking, two important techniques for solving coding problems. The best thing is that he explains the solution in depth. Examples from the CLRS book are also covered in this course, which one can refer to know more about concepts.

Great collection. I really found dynamic programming tough, its not easy to master, every question seems to be different question but after reading Grokking Algorithm book and joining Grokiing Dynamic Programming course on Educative, I am feeling much more confident on solving Dynamic programming problems, especially the Knapsack ones.
