Who is this book for?
I recommend this to readers like this.

- Job seekers in IT fields / prospective developers
- Developers preparing for a job change
- Students preparing for an algorithm competition


[Book Features]
Provides core algorithms and solutions to past exam questions required for coding tests.
We thoroughly analyzed the types of questions from previous exams at Kakao, Samsung, and Line, which are preferred by all job seekers, and organized the questions by algorithm type.

- Analysis of past exam questions from 2016 to the latest exam questions from 2020
Part 1 contains analysis of coding test questions from major IT companies that job seekers want to work for, and trends in past exam questions.
Read Part 1 and figure out the types of problems the company you want to go to has.

- Explanation of 8 algorithm theories
Study the second part of algorithm theory according to the exam trends of the company you want to work for.
Let's learn problem-solving methods by looking at the practical problem solutions that follow the theory.

- Solutions to past exam questions
Let's review the 'Algorithm summarized in one page' of each chapter and solve past exam questions by type.


- Review weak areas
Let's try to solve the previous questions from Part 3 at least three times.
First, solve the problem and identify your weak points. Then, find the weak points and solve them on a site that provides additional guidance.


- Additional Offer 1: Guide to Successful Employment
This book is a guide to help job seekers find successful employment.
Although the content is mainly about code, it also provides detailed interview tips and additional study guide sites, so be sure to refer to them.

- Additional Offering 2: Python Grammar for Coding Tests
Even if you are a beginner in Python, don't worry. Just read the appendix to find the Python grammar needed for the coding test.

- Additional Offer 3: C/C++ and Java users are also OK!
In addition to Python, we also provide C/C++ and Java code!
