C# Data Structures and Algorithms

By: Marcin Jamro

Overview of this book

Data structures allow organizing data efficiently. They are critical to various problems and their suitable implementation can provide a complete solution that acts like reusable code. In this book, you will learn how to use various data structures while developing in the C# language as well as how to implement some of the most common algorithms used with such data structures. At the beginning, you will get to know arrays, lists, dictionaries, and sets together with real-world examples of your application. Then, you will learn how to create and use stacks and queues. In the following part of the book, the more complex data structures will be introduced, namely trees and graphs, together with some algorithms for searching the shortest path in a graph. We will also discuss how to organize the code in a manageable, consistent, and extendable way. By the end of the book,you will learn how to build components that are easy to understand, debug, and use in different applications.

Circular-linked lists

In the previous section, you have learned about the double-linked list. As you can see, the implementation of such a data structure allows for navigating between the nodes using the Previous and Next properties. However, the Previous property of the first node is set to null, as is the Next property of the last node. Do you know that you can easily expand this approach to create the circular-linked list?

Such a data structure is presented in the following diagram:

Here, the Previous property of the first node navigates to the last one, while the Next property of the last node navigates to the first. This data structure can be useful in some specific cases, as you will see while developing a real-world example.


It is worth mentioning that the way of navigating between nodes does not need to be implemented as properties. It can also be replaced with methods, as you will see in the example within the following section.
