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.

Queues

A queue is a data structure that allows you to add a new element only at the end of the queue (referred to as an enqueue operation) and to get an element only from the beginning of the queue (a dequeue operation). For this reason, a queue is consistent with the FIFO principle, which stands for First-In First-Out.

Imagine a queue

If you want to better imagine a queue, let’s take a break from learning data structures and algorithms, wear your favorite jacket, and go to a shop in the vicinity. You buy your favorite ice cream, and you see five people waiting for checkout. Oh no... You are the last one, so you need to wait until the first, second, third, fourth, and fifth person pay. These lines in shops can be frustrating! In general, new people stand at the end of the line, and the next person is taken to the checkout from the beginning of the line. No one is allowed to choose a person from the middle and serve them in a different order. The queue data structure operates...
