Coding Test Practice Test (with Java)
Are you short on time to prepare for the coding test? We have compiled the most frequently appearing types of questions. These are the types that will definitely appear on the test. Try solving them and leave a question and we will respond right away!
What you will gain after the course
Array/Two-dimensional array, String, Math
Map/Set, Sort, Binary Search, Priority Queue, DP
DFS, BFS, Two Pointers, LinkedList
Only practical problems!
Java coding tests, faster and more accurate.
How should I prepare for the coding test? ✅
This lecture! 📖
This is a lecture on a practical mock exam for a coding test using the Java language.
- You can solve the latest coding test problems .
- You can practice solving the most common types of problems using formulas .
- The problems are organized by frequency of appearance in practical problems .
- Identify key problem types and save time on solving them .
- First, try to solve the problem, and then look at the coding solution.
A sneak peek of the lecture 👀
In actual coding tests, the frequency of appearances is as follows.
- String/Array
- BFS/DFS
- DP
- ...
In this lecture
1. We will mainly solve problems related to String/Array, Greedy, Comparator, Set, and Stack&Queue.
2. By practicing solving frequently appearing DP, BFS/DFS problems using formulas, you can identify key problem types and save problem-solving time.
Easier, faster, and more accurate with the formula!
Expected Questions Q&A 💬
Q. How are classes conducted?
First, you will download the problem book for each chapter and then solve the problems.
You can solve the problems in the workbook in advance and then watch the video.
The source code is also available on github.
Q. Is this a course that non-majors can also take?
This course is designed for anyone preparing for a coding test in Java. Anyone with a basic understanding of Java can learn it.
There's no longer a distinction between majors and non-majors. Both majors and non-majors must pass a coding test to be considered for an interview. As long as you have the skills and can pass the coding test, everyone has a chance!
Q. What are the benefits of taking this course?
This study focused on the most common problem types in coding tests. These days, String/Array and Map-related content almost always appear in the first stage of most coding tests. Therefore, we focused on String/Array, DP, and BFS/DFS, which are highly likely to appear on the test .
Q. Is there anything I need to prepare before attending the lecture?
Before attending the lecture, you need to have a basic understanding of the Java language and Eclipse tools set up. After setting up Eclipse with the Java version, you can solve the problems before attending the lecture. The source code is also available on GitHub.
Q. What level of content is covered in the class?
The level of the class content ranged from beginner to intermediate level.
These aren't the ultimate questions. They're structured at a level anyone can understand and solve. Ultimately, they're similar types of questions.

100% enrolledThe content is good. However, the instructor's materials are a bit... It seems like he brought the algorithm from somewhere overseas. There are many cases where it is difficult to understand because the explanation in the problem book is too insufficient, and there are many examples written in English, and the example parameters are shortened and changed during the lecture... Even if you prepare the method in advance to solve the problem and follow the instructor's problem, it is sometimes useless. For reference, I am proceeding by solving the problem explanation book and listening to the lecture.

Hello dhdh9224@gmail.com~ Thank you for your course review. 1. The questions are of a foreign type. => Most of the current domestic problems are variations of foreign types. 2. Some English examples If you did not understand the questions due to some English examples, I will update them. If there are parts with a lot of English, or parts that you did not understand because the explanation in the text is short, I will supplement the problem book and upload them again. These problems are of a type that almost always appears in real life. If there are any missing parts, I will update them sequentially from the beginning and write down the date. Thank you.
