Data Structures are an essential topic for developers. All kinds of software and programs we write heavily rely on data and data structures in one way or another. Having a good understanding of data structures is going to be helpful in building robust applications.

In this free illustrated course, you will learn everything you need to know about Data Structures. We will start with the introduction to the data structures, understanding what they are, why we need them, what are the most common data structures and why picking the right data structure is important. With that out of the way, we will learn about the common data structures i.e. Arrays, Linked Lists, Stacks, Queues, Hash Tables, Trees, Heaps, and Graphs. For each of these data structures, we will first learn what the data structure is about, we will look behind the scenes to understand how it works, we will understand the common operations which can be performed on the given data structure, common use cases, and the complexity of different operations on that data structure.

This course also comes with an extra video to give you an introduction to algorithms, algorithmic complexities, common algorithmic complexities, and a comparison between each.
