New techniques for building more secure, reliable, high-performance software, from the renowned creator of the C++ STL • • A truly foundational book on the discipline of generic programming: how to write better software by mastering the development of abstract components. • Based on Alexander Stepanov's breakthrough lectures to programmers at Adobe and throughout Silicon Valley. • For serious software developers, architects, and engineers, the perfect complement to Knuth's theory and Stoustrup's practice. Elements of Programming is the next breakthrough book for serious practitioners seeking ways to write better software. In this book, Alexander Stepanov - the legendary architect and creator of the C++ Standard Template Libraries - focuses on the discipline that offers the greatest potential for improving contemporary software: the proper development of abstract components. Drawing on his enormously popular lectures to programmers at Adobe and throughout Silicon Valley, Stepanov illuminates crucial techniques of generic programming, specifically focusing on abstraction as the key to secure, reliable, and high-performance software. Together with co-author and ACM Fellow Paul McJones, Stepanov shows programmers how to use mathematics to compose reliable algorithms from components, and to design effective interfaces between algorithms and data structures. Topics covered in Elements of Programming include: transformations, associative operations, linear orderings, ordered algebraic structures, iterators, coordinates and coordinate structures, copying algorithms, rearrangement, sorting, and much more. This book requires an understanding of mathematics, but is consistently focused on identifying superior solutions to practical programming problems. Stepanov and McJones illuminate their concepts and techniques with C++ code, but the techniques are equally applicable to a wide range of contemporary object-oriented languages.

This book is about coding interview questions from software and Internet companies. It covers five key factors which determine performance of candidates: (1) the basics of programming languages, data structures and algorithms, (2) approaches to writing code with high quality, (3) tips to solve difficult problems, (4) methods to optimize code, (5) soft skills required in interviews. The basics of languages, algorithms and data structures are discussed as well as questions that explore how to write robust solutions after breaking down problems into manageable pieces. It also includes examples to focus on modeling and creative problem solving. Interview questions from the most popular companies in the IT industry are taken as examples to illustrate the five factors above. Besides solutions, it contains detailed analysis, how interviewers evaluate solutions, as well as why they like or dislike them. The author makes clever use of the fact that interviewees will have limited time to program meaningful solutions which in turn, limits the options an interviewer has. So the author covers those bases. Readers will improve their interview performance after reading this book. It will be beneficial for them even after they get offers, because its topics, such as approaches to analyzing difficult problems, writing robust code and optimizing, are all essential for high-performing coders.

If you'd like to know what some of history's greatest thinkers and achievers can teach you about awakening your inner genius, and how to find, follow, and fulfill your journey to greatness, then you want to read this book today. You can score in the highest ranges of IQ...and fail to succeed in life. You can work incredibly hard...and never realize your dreams. You can stumble across beautiful opportunities...only to watch them wither and die. There's something else--something considered unfathomable by many--that lies behind greatness. And in Awakening Your Inner Genius, you're going to be taken on an adventure to discover what that is, and how you can use it to transform your life. You see, genius is a path, not a gift. Studies of history's greatest geniuses have shown that there is a "genius code," if you will. A combination of very specific traits that we can develop in ourselves, and thus, operate at a genius level. In this book, you're going to learn things like... Why IQ, opportunities, and working toward that magical goal of 10,000 hours don't comprise the whole story of great achievers, and what else is needed to walk in the footsteps of our greatest geniuses. How to view and deal with the world as Leonardo da Vinci did, and embrace the one trait that most accounted for his incredible genius and talents. Lessons from Nikola Tesla on why imagination is so vital to awakening your inner genius, and insights into the real "secret" to creativity, as explained by people like Jobs, Picasso, Dali, and Twain. How Thomas Edison was able to go from a mischievous academically challenged kid to the world's most successful inventor, and how you too can formulate and realize goals like he did. The secret to Alexander the Great's superhuman drive and work ethic, and how you can inspire yourself to pursue your own goals and dreams with the same vigor and tenacity. What geniuses like Elizabeth I can teach you about the importance of individualism in your journey to greatness, and how to strengthen your will to break away from conventions, ignore the naysayers, and stay true to your vision and principles. How Hippocrates' epic quest to reform medicine in ancient Greece was fueled by his unparalleled judgment, and how you too can sharpen your ability to make the right decisions at the right times and thus move closer to your dreams, one good call at a time. And much, much more... Imagine for a moment how this could change your life. If you dream of escaping the nine-to-five and striking out on your own, imagine if you knew with certainty that you would succeed. If you don't like where some aspect of humanity is going, imagine if you could do something amazing about it. If you have a stubborn desire to reach out into our culture and write "I was here," imagine if nothing could stop you. So, is the journey to genius right for you? Well, ask yourself the following questions. Who are you, really, and what are you really capable of? What is your calling, and what might happen in the world if you found out? If these questions ignite a spark of curiosity in you, then empower yourself to explore their meaning and magnitude. Read this book today and discover what it really takes to find and follow your bliss, and how to use the lessons passed down to us by some of history's greatest geniuses to systematically rise to top of your fields, activities, and endeavors.

This book builds a bridge between the recreational world of algorithmic puzzles (puzzles that can be solved by algorithms) and the pragmatic world of computer programming, teaching readers to program while solving puzzles. Few introductory students want to program for programming's sake. Puzzles are real-world applications that are attention grabbing, intriguing, and easy to describe. Each lesson starts with the description of a puzzle. After a failed attempt or two at solving the puzzle, the reader arrives at an Aha! moment -- a search strategy, data structure, or mathematical fact -- and the solution presents itself. The solution to the puzzle becomes the specification of the code to be written. Readers will thus know what the code is supposed to do before seeing the code itself. This represents a pedagogical philosophy that decouples understanding the functionality of the code from understanding programming language syntax and semantics. Python syntax and semantics required to understand the code are explained as needed for each puzzle. Readers need only the rudimentary grasp of programming concepts that can be obtained from introductory or AP computer science classes in high school. The book includes more than twenty puzzles and more than seventy programming exercises that vary in difficulty. Many of the puzzles are well known and have appeared in publications and on websites in many variations. They range from scheduling selfie time with celebrities to solving Sudoku problems in seconds to verifying the six degrees of separation hypothesis. The code for selected puzzle solutions is downloadable from the book's website; the code for all puzzle solutions is available to instructors.
