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.

Arrays

Let’s start with an array, which was the main topic of Chapter 3, Arrays and Sorting. You can use this data structure to store many data of the same type, such as int, string, or a user-defined class. The important assumption is that the number of elements in an array cannot be changed after initialization. Moreover, arrays belong to random access data structures. This means that you can use indices to get access to the first, the middle, the n-th, or the last element from the array.

You can benefit from a few variants of arrays – namely, single-dimensional, multi-dimensional, and jagged arrays, also referred to as an array of arrays. All of these variants are shown in the following illustration:

There are a lot of applications for arrays and, as a developer, you have probably already used this data structure many times. In this book, you saw how you can use it to store various data, such...
