Kotlin Brain Teasers
Level up your Kotlin the fun way! Solve mysteries, dodge traps, and banish bugs. Sharpen your critical thinking to ace interviews and ship rock-solid code. Can you outsmart the Kotlin compiler? Detect, deduce, and diagnose your way to clearer code and expert insights. Escape type-system traps and navigate logic labyrinths. Challenge your skills and quiz your friends with fun Kotlin facts, and power up your code with nuanced mastery of data types, functions, and programming techniques. Stay sharp, know your threats, and reason critically to fix bugs before they happen. Laugh at unexpected outcomes and puzzle over awkward edge cases, then ace your next interview with memorable payoffs that simplify key concepts in Kotlin and computer science. Put the fun in functions and laugh while you learn with programming puzzles that challenge your intuition and sharpen your skills. Guess each simple program's output--if you can--then run the code or turn the page to find out what's not as it seems. Deepen your understanding of key data types and put computer science in context as you make deductions and discoveries that will upgrade your apps. Play around and break things to uncover the deliberate design decisions behind Kotlin's unexpected quirks and reveal the why, not just the what. Take on the type system and smuggle null values past the compiler's defenses. Overload operators and turn math on its head as you crack floating-point conundrums. Think like a computer and predict your program's path when you test the limits of control-flow keywords. Harness the power of iteration and immutability to tame devious data and curate collections with confidence. Unravel ambiguous lambda functions and streamline inscrutable syntax. Dodge destructuring dilemmas, spot sneaky shadowing, and know the dynamic difference between members and extensions. Prepare for interviews, tests, competitions, real-world projects, and more with powered-up problem-solving proficiency, improved coding confidence, and lasting Kotlin lessons. Most of all, have fun! What You Need: Run the code in your head, in your IDE, or in the free online Kotlin Playground. The puzzles were written and tested with Kotlin 2.1.20 on the Java Virtual Machine, but they'll work on any recent version and platform. You don't need any additional dependencies.
Pandas Brain Teasers
Author: Miki Tebeka

Publisher: The Pragmatic Programmers LLC
Release Date: 2021-08-30
This book contains 25 short programs that will challenge your understanding of Pandas. Like any big project, the Pandas 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. Working with data is central to nearly everything we do, from disease contact tracing and analyzing health records to smart meters that track utility consumption behavior. With the power of Python's pandas library, you can process and analyze this data in a highly efficient and simple-to-understand way. And with 25 brain teasers designed to turn this technology's quirks into a teaching opportunity, you'll be honing your data science skills while having fun at the same time. Following a simple format, you'll challenge yourself and your understanding of pandas. Read a short Python program that uses pandas, try to guess the output, run the code yourself, and then go to the next page for an explanation of the solution. From common pitfalls and hidden gotchas to unexpected twists and turns, you'll deepen your understanding of pandas, learn to write more efficient code, and reduce the number of bugs in the software you develop. You may even impress your colleagues and your employers, both present and future. Learn the tricks of the trade with Python's pandas, in one of the most fun and creative ways around. What You Need: To run the code you'll need Python version 3.8 or upper and Pandas version 1.0 or upper installed. We use Python version 3.8.3 and Pandas version 1.0.5; the output might change in future versions.
Rust Brain Teasers

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.
