Hands-On Data Structures and Algorithms with Kotlin

By: Chandra Sekhar Nayak, Rivu Chakraborty

Overview of this book

Data structures and algorithms are more than just theoretical concepts. They help you become familiar with computational methods for solving problems and writing logical code. Equipped with this knowledge, you can write efficient programs that run faster and use less memory. Hands-On Data Structures and Algorithms with Kotlin book starts with the basics of algorithms and data structures, helping you get to grips with the fundamentals and measure complexity. You'll then move on to exploring the basics of functional programming while getting used to thinking recursively. Packed with plenty of examples along the way, this book will help you grasp each concept easily. In addition to this, you'll get a clear understanding of how the data structures in Kotlin's collection framework work internally. By the end of this book, you will be able to apply the theory of data structures and algorithms to work out real-world problems.

Introduction to data structures

We solved the previous example by taking a few steps, such as asking all students to stand in a queue and, once a student got candy, we moved them to a separate group. We could have also done the same task without asking them to maintain a queue or separating them into a separate group once they got the candy. But we did that to make the task go smoother. Of course, we could have done the task without these two sub-tasks, but that would have created a lot of confusion and made it tedious to finish the task on time.

If we consider that example, we can treat candies and students as data. And to solve the problem given by the teacher, we first structured the data and solved it with ease. This is what we call data structures in computer science.

In this book, we'll cover the most commonly used data structures such as an array, string, list, linked...
