C# Data Structures and Algorithms - Second Edition

By: Marcin Jamro

Overview of this book

Building your own applications is exciting but challenging, especially when tackling complex problems tied to advanced data structures and algorithms. This endeavor demands profound knowledge of the programming language as well as data structures and algorithms – precisely what this book offers to C# developers. Starting with an introduction to algorithms, this book gradually immerses you in the world of arrays, lists, stacks, queues, dictionaries, and sets. Real-world examples, enriched with code snippets and illustrations, provide a practical understanding of these concepts. You’ll also learn how to sort arrays using various algorithms, setting a solid foundation for your programming expertise. As you progress through the book, you’ll venture into more complex data structures – trees and graphs – and discover algorithms for tasks such as determining the shortest path in a graph before advancing to see various algorithms in action, such as solving Sudoku. By the end of the book, you’ll have learned how to use the C# language to build algorithmic components that are not only easy to understand and debug but also seamlessly applicable in various applications, spanning web and mobile platforms.

Dictionaries and Sets

This chapter focuses on data structures related to dictionaries and sets. Applying these data structures makes it possible to map keys to values and perform fast lookup, as well as to make various operations on sets. To simplify your understanding of dictionaries and sets, this chapter contains illustrations and code snippets, along with detailed descriptions.

First, you will learn about both non-generic and generic versions of a dictionary, which is a collection of pairs, each consisting of a key and a value. Then, a sorted variant of a dictionary will be presented. The remaining part of this chapter will show you how to use hash sets, together with a “sorted” set variant. Is it possible to have a “sorted” set? You’ll learn more later in this chapter.

In this chapter, the following topics will be covered:

  • Hash tables
  • Dictionaries
  • Sorted dictionaries
  • Hash sets
  • Sorted” sets
