I am deeply indebted to my acquisition editors, Ashish Bhanushali and Subho Gupta, and the project co-ordinator, Kinjal Bari, who gave me the chance to write my first book. It was a great gamble for them to choose me because I had no prior experience in book publishing.

I would like to express my deepest gratitude to my responsible editor, Ruchita Bhansali. She is a very helpful and responsible editor who put in a lot of effort in this book and led me through the process of publishing this book.

I am also grateful to all the reviewers from different technical backgrounds for their comments, opinions, and valuable suggestions for this book. These suggestions have definitely enriched and expanded the content of this book. Thanks to them for making this book interesting and enriching.

Last but not least, I would like to take this opportunity to give credit to my parents and my girlfriend, Fanny. Without their understanding and support, I would not have had the courage to accept this new challenge.
