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.

Learning about algorithms

In computer programming, the sole purpose of building any software is to solve a problem existing in the real world and make the world a better place to live in. When we talk about a solution to a problem, it's obvious that we're talking about the procedure to be followed to solve the problem.

Let's consider a case where your teacher comes to you and gives you a bunch of candy, asking you to distribute it equally among your classmates. If you consider this as a problem and try to achieve it with ease, then you might do it as follows:

  1. Count the number of candies you have.
  2. Count the number of students present in your class.
  3. Calculate how many candies should be given to each student.
  4. Ask all of the students form a queue so that no student can take the required candies twice.
  5. Start distributing the candies to each student.
  6. Maintain a separate...
