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.

In the previous section, you learned about the Hashtable class, a non-generic variant of the hash table-related classes. However, it has a significant limitation, because it does not allow you to specify a type of a key and a value. Both the Key and Value properties of the DictionaryEntry class are of the object type. Therefore, you need to perform boxing and unboxing operations, even if all the keys and values are of the same type. If you want to benefit from the strongly typed variant, you can use the Dictionary generic class, which is the main subject of this section.

First of all, you should specify two types, namely a type of a key and a value, while creating an instance of the Dictionary class. Moreover, it is possible to define the initial content of the dictionary using the following code:

Dictionary<string, string> dictionary = new()
    { "Key #1", "Value #1" },
    { "Key #2&quot...
