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 collections

In programming, the word "framework" generally refers to a structure underlying a system that can be used within the system to perform a set of similar operations. Thus, we can think of a framework as a collection of libraries/APIs.

Similarly, the collections framework provides developers with a set of APIs to perform common data/data structure-related operations (which can be called data operations). The collections framework contains a few of the most commonly needed interfaces to deal with data structures and their common concrete implementations. You can always create your own custom implementation of a Collection interface. The collections framework also defines the most common algorithms, including the following:

  • Searching
  • Sorting
  • Insertion
  • Deletion
  • Manipulation

All the lists, maps, and sets we use in our programs every day are part...
