Welcome to the world of data structures using C++. This book aims to be your comprehensive guide to understanding and mastering the art of analysing the effectiveness of algorithms and its underlying concepts. Data structures play a pivotal role in solving complex problems, by analysing the complexity of algorithms in terms of time and spaces. This book is structured in a way that allows you to progress systematically through each chapter, building your knowledge and skills step by step. However, you can also use it as a reference guide, jumping directly to specific topics or revisiting concepts you want to reinforce. To make the most out of this book, a basic understanding of programming concepts and syntax is recommended. Familiarity with C++ will be beneficial, but even if you are new to the language, we will guide you through the necessary concepts. A curious and explorative mind, coupled with a willingness to practice, experiment, and solve problems, will be your greatest assets on this learning path. So, let's begin this exciting adventure together, and may you find joy in the art of data manipulation and the elegance of efficient algorithms.
