This book contains 25 short programs that will challenge your understanding of Go. Like any big project, the Go developers had to make some design decisions that at times seem surprising. This book uses those quirks as a teaching opportunity. By understanding the gaps in your knowledge, you'll become better at what you do. Some of the teasers are from the author's experience shipping bugs to production, and some from others doing the same. Teasers and puzzles are fun, and learning how to solve them can teach you to avoid programming mistakes and maybe even impress your colleagues and future employers. Programmers love the Go (golang) programming language because of its efficiency and simple tooling. But that doesn't mean programming in Go is without challenges, like hidden dependencies that trip up the compiler and interesting string type conversions that differ from languages like Python. Work your way through 25 short brain teasers, and learn the nuances of Go in one of the most fun and creative ways around. Challenge yourself and challenge your assumptions to gain a more in-depth understanding of integers, strings, Unicode, compiler behavior, and a variety of subtle programming gotchas that might otherwise trip you up. Just read a short program written in Go, try to guess the output, run the code yourself, and then go to the next page for an explanation of the solution. By working through these brain teasers, you'll tighten up your Go programming skills and have lots of fun at the same time. Taken from real-world, programming problems, conference talks, and meetup quizzes, these brain teasers provide an effective learning tool that's as enjoyable as it is educational. What You Need: This book assumes you know Go at some level and have experience programming with it. *NOTE:* We use Go version 1.14.1 to run the code; the output might change in future versions. You will need a working Go environment, you can download it from https://golang.org/dl. You will probably want a good IDE for Go, two of the most popular ones are Visual Studio Code and GoLand.

The Rust programming language is consistent and does its best to avoid surprising the programmer. Like all languages, though, Rust still has its quirks. But these quirks present a teaching opportunity. In this book, you'll work through a series of brain teasers that will challenge your understanding of Rust. By understanding the gaps in your knowledge, you can become better at what you do and avoid mistakes. Many of the teasers in this book come from the author's own experience creating software. Others derive from commonly asked questions in the Rust community. Regardless of their origin, these brain teasers are fun, and let's face it: who doesn't love a good puzzle, right? What better way to exercise your brain and increase your Rust programming knowledge than with a collection of dynamic brain teasers? As you read through each of these puzzles and try to work out the answers, you'll not only learn about Rust's unique quirks and peculiarities, you'll also have loads of fun along the way. Dive right in and get started with example code and sample problems that cover numbers and text, shadowing and memory, and everything in between. Try to figure out why a particular program won't compile, why it produces unexpected output, or why it panics and terminates with an error message. Once you've run the code and read the answer, it's time to get to the heart of the matter with a detailed explanation. Learn why a program produced the result it did, and discover how similar issues might affect the code you write in your own programs, even in production. Sourced from engaging discussions within the Rust community, real-world problems, and even reader feedback, these challenges will certainly surprise, enlighten, and entertain you. Are you ready to experience Rust like never before? Then sharpen your brain and get ready for a challenge! What You Need: This book assumes you have some knowledge of the Rust programming language. To work through the brain teasers in this book, you'll need a working Rust environment on any platform. You can install Rust by visiting https://rustup.rs/. You'll also need a text editor or Rust-friendly IDE.

The Go programming language is a simple one, but like all other languages ithas its quirks. This book uses these quirks as a teaching opportunity. Byunderstanding the gaps in your knowledge - you'll become better at what you do.There's a lot of research showing that people who make mistakes during thelearning process learn better than people who don't. If you use this approachat work when fixing bugs - you'll find you enjoy bug hunting more and become abetter developer after each bug you fix.These teasers will help you avoid mistakes. Some of the teasers are from my ownexperience shipping bugs to production, and some from others doing the same.Teasers are fun! We geeks love puzzles and solving them. You can also use theseteasers to impress your co-workers, have knowledge competitions and becomebetter together.Many of these brain teasers are from quizzes I gave at conferences andmeetups. I've found out that people highly enjoy them and they tend to liventhe room.At the beginning of each chapter I'll show you a short Go program and will askyou to guess the output. The possible answers can be: - Won't compile- Panic- Deadlock- Some output (e.g. `[1 2 3]`)Before moving on to the answer and the explanation, go ahead and guess theoutput. After guessing the output I encourage you to run the code andsee the output yourself, only then proceed to read the solution andthe explantation. I've been teaching programming for many years and found thiscourse of action to be highly effective

To succeed in life, you must 'think outside the box'. This cliché is used to describe creative, non-standard approaches to problem solving. But how does one learn to 'think outside the box'? Unfortunately, there is no simple answer. Author Kiran Srinivas believes that you can significantly improve your thinking abilities, and this book will force you to think in ways you never have before. By sheer practice, you can increase your ability to think creatively. Many of the puzzles in this book will take hours, if not days, to solve, but be encouraged, a middle-school education is sufficient to answer almost all of the puzzles. There are many interview puzzles, and if you plan to interview at an investment bank, consulting firm, high-tech firm, or in any other related field, absorb what 'Brain Teasers' has to offer, as it can be the deciding factor in getting that offer.

Don't think too hard or you'll never solve these logic puzzles and riddles. The answers to all 187 are easy once you catch the tricky wording. How can you tie a knot in a napkin by holding one end in each hand without letting go of it? Impossible, you say (or your friends will say, if you bet them). But: Cross your arms and hold a tip of the napkin in each hand. When you uncross your arms, the knot will be formed! Now try this riddle: I climbed up a cherry tree, where I found cherries. I did not pick cherries, nor did I leave cherries. How can you explain this? Answer: I climbed up a cherry tree with two cherries in my hand. I picked only one. I left the other one on the tree. I did not "pick cherries," because I "picked a cherry." Take this dare: My bird can fly faster than any supersonic plane. Here's how: If you put my bird inside any plane and make it fly in the same direction as the plane, it will go faster than the plane. 96 pages, 52 b/w illus., 5 3/8 x 8 1/4.
