Algorithms and Data Structures in C# (.NET)

The book "Algorithms and Data Structures in C# (.NET)" is a practical guide that helps developers master fundamental Computer Science concepts on the .NET platform. The author, Andrey Sokolov, organizes the material so that the reader not only memorizes ready-made solutions but learns to choose and design algorithms for specific tasks.

What this book is about

The book covers a full range of topics necessary for confident work with data:

• Basic Structures: arrays, lists, stacks, queues, hash tables and their implementation in C#.
• Trees and Graphs: binary search trees, AVL trees, red-black trees, graph traversals (BFS, DFS), Dijkstra's and A* algorithms.
• Sorting and Searching: from bubble sort and quicksort to binary search and interpolation search.
• Dynamic Programming: knapsack problems, finding the longest common subsequence, recursion optimization.
• Memory Management: managing reference and value types, garbage collection, impact on performance.

Who this book is for

• Beginning C# developers who want to deepen their knowledge of algorithms.
• Junior and Middle developers preparing for technical interviews.
• Students and teachers studying Computer Science on the .NET platform.
• Programmers transitioning from other languages to C# who want to master its idioms.

What you will learn

After reading the book, you will be able to:

• Implement data structures from scratch, understanding their internal workings.
• Analyze the time and space complexity of algorithms (Big O).
• Use standard .NET collections (List, Dictionary, HashSet, Queue, Stack) deliberately, knowing their strengths and weaknesses.
• Solve typical interview problems in C# (LeetCode, Codeforces, HackerRank).
• Design high-performance code using Span, Memory, and ValueTask.

Each chapter contains ready-made examples in C# as well as assignments for independent work. The book is written in a lively style, without excessive academicism, making it useful both for self-study and for use as a reference.

"Algorithms and Data Structures in C# (.NET)" will become your reliable assistant in the world of professional development on the Microsoft platform.
