Dedication

I want to dedicate this book to my parents and my lovely fiancée, who have always supported me and given me their best, so I can not only reach my goals, but also achieve them successfully. Without them, nothing would have been possible. Thank you for always being there for me.

I would like to dedicate this book to my grandmother, who unfortunately passed away during the development of the book and couldn't see the finished version. Even when she didn't even understand the language or what was being described, she always asked about its progress.
