The Complete Coding Interview Guide in Java

By: Anghel Leonard

Overview of this book

Java is one of the most sought-after programming languages in the job market, but cracking the coding interview in this challenging economy might not be easy. This comprehensive guide will help you to tackle various challenges faced in a coding job interview and avoid common interview mistakes, and will ultimately guide you toward landing your job as a Java developer. This book contains two crucial elements of coding interviews - a brief section that will take you through non-technical interview questions, while the more comprehensive part covers over 200 coding interview problems along with their hands-on solutions. This book will help you to develop skills in data structures and algorithms, which technical interviewers look for in a candidate, by solving various problems based on these topics covering a wide range of concepts such as arrays, strings, maps, linked lists, sorting, and searching. You'll find out how to approach a coding interview problem in a structured way that produces faster results. Toward the final chapters, you'll learn to solve tricky questions about concurrency, functional programming, and system scalability. By the end of this book, you'll have learned how to solve Java coding problems commonly used in interviews, and will have developed the confidence to secure your Java-centric dream job.

Summary

This was one of the tough chapters of this book and a must-read for any technical interview. Trees and graphs are such wide, wonderful, and challenging topics that entire books have been dedicated to them. However, when you have to prepare for an interview, you don't have the time to study tons of books and deep dive into every topic. This is exactly where the magic of this chapter comes into the picture: this chapter (just like the entire book) is totally focused on the fact that you must achieve your goal: ace a technical interview.

In other words, this chapter contained the most popular tree and graph problems that may be encountered in technical interviews, along with meaningful figures, comprehensive explanations, and clear and clean code.

In the next chapter, we'll tackle problems related to sorting and searching.
