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.

Sorted dictionaries

Both non-generic and generic variants of the hash table-related classes do not keep the order of the elements. For this reason, if you need to present data from the collection sorted by keys, you need to sort them before presenting them. However, you can use another data structure, known as a sorted dictionary, to solve this problem and keep keys sorted all the time. Therefore, you can easily get the sorted collection if necessary.

Imagine a sorted dictionary

If you want to better imagine a sorted dictionary, remember the times from a dozen or so years ago, when the internet was not as popular and widespread as it is today, and at home there was a book on your shelf that allowed you to learn the meaning of a word in another language. How does it work? Let’s assume that you have a Polish-English dictionary, thanks to which you can find out how to translate a specific word from Polish to English, such as cześć to hello.
