Algorithms and Data Structures in Kotlin

The book "Algorithms and Data Structures in Kotlin" is a practical guide for developers who want to deepen their knowledge of algorithmization and efficient data management using the modern Kotlin language. The author, experienced developer and teacher Igor Smirnov, offers a structured approach to learning fundamental and advanced concepts, accompanying each topic with clear code examples, diagrams, and exercises.

What is this book about?

The book covers a wide range of topics — from basic data structures (arrays, lists, stack, queue, hash tables) to complex algorithms (sorting, search, graph algorithms, dynamic programming). Each chapter contains:

• A theoretical introduction explaining the principles of operation.
• Implementation in Kotlin, taking into account language features (null safety, extension functions, coroutines).
• Analysis of time and space complexity (Big O notation).
• Practical problems and their solutions to reinforce the material.

Who is this book for?

• Beginner developers who have already mastered the basics of Kotlin and want to move on to more complex topics.
• Juniors and mid-levels preparing for technical interviews — the book includes an analysis of typical interview problems.
• Android developers looking to optimize their applications using efficient algorithms.
• Anyone interested in Kotlin as a language for backend development (Ktor, Spring) and wanting to write clean, performant code.

What will you learn?

• How to choose a data structure depending on the task.
• Implementation of sorting algorithms (quick sort, merge sort, heap sort) and search algorithms (binary search, interpolation search).
• Working with trees (BST, AVL, red-black trees) and graphs (BFS, DFS, Dijkstra's algorithm).
• Basics of dynamic programming and greedy algorithms.
• Using Kotlin functional approaches (lambdas, sequences) for elegant algorithmic problem-solving.
• Testing and debugging algorithms using JUnit and Kotest.

This book will become your reliable companion in mastering algorithms and data structures in Kotlin — a language that combines conciseness and power. Whether you are preparing for an interview or striving to write more efficient code, you will find everything you need here.
