This was my first time preparing for a coding test, so I had no idea how to prepare. I didn't know much about algorithms, and I didn't know which website to study on, which problems to solve, or how to study. The lecture helped me a lot because it explained everything step by step! In particular, it didn't tell me to just memorize the solution to the problem, but showed me various solutions, so it was good to study with a solution that suited me. And I panicked because I ran out of time while solving a problem on my own, but the video explained the time complexity, so I understood why it happened. Thank youใ ใ

In my opinion, this is the most ideal introduction to coding tests. The lecture materials are also very well-made, so it is good for self-study later. I hope that in the future, like math online lectures, problem-solving sections or advanced concept sections will be made!

The lecture is the best.. Especially when explaining the concept of combinational algorithms, the relationship between for loops and recursive functions was very good. When solving combinational problems with recursion, I simply added 1 to the index and set the level to set the termination condition, and I solved it. However, since I solved it without fully understanding it, I made mistakes in the implementation, and I thought that recursion itself was too difficult and I didn't want to solve the problem. However, after listening to this lecture, I think I accurately grasped and understood the concept itself. It was a very satisfying lecture to the point that I thought it would have been better if I had taken this lecture sooner. Thank you so much.

Actual Kakao Coding Test Commentary for Improving Practical Skills
In this lecture, we do not simply solve the problems for you, but rather teach you how to solve the problems yourself.
We provide overwhelmingly high-quality explanatory lectures that cover everything from the thought process of deriving a solution to the actual answers and explanations.
All explanations provided in this lecture follow these steps.
Problem Approach -> Presenting Various Solutions -> Verifying and Explaining Each Solution -> Implementing Possible Solution Codes -> Supplementary Explanations
These are actual student reviews from those who have already experienced an improvement in their problem-solving skills.
These are 100% genuine student reviews written before any course review events were held.
โญ ๏ธI am confident that this will be the best lecture for those who have no idea how to solve problems โญ๏ธ
We have selected only the essential algorithms absolutely necessary for coding tests and included them all in this course.
From meticulous theoretical explanations to relevant example codes, we provide everything.
Algorithm theory? It's not yours unless you solve it yourself.
You cannot solve problems simply by learning the theory. It is structured so that you can develop problem-solving skills for each algorithm by learning the algorithm theory and then working through example problems together.
Can you pass just by solving algorithm practice problems?
That is why we have prepared actual coding test questions from major corporations.
From approaching actual large-corporation coding test problems to solutions and explanations, this is structured to help you build practical real-world skills.
Who is this course right for?
Someone who is just starting to study for coding tests
People who have studied for coding tests but get stuck as soon as they see a problem
People who want to solve coding test problems logically rather than by intuition.
People who want to study coding tests systematically
Need to know before starting?

This is a lecture where you can feel the sincerity in the lecture composition. The materials and explanations are both so good that it gives me strength to study algorithms. Thank you for developing such a good lecture.
Hello, Algochemy! Thank you for your valuable review. I prepared the overall structure of the lecture carefully, and I'm glad it was helpful! If you have any questions during your studies, feel free to ask me anytime! Fighting until the end :)

Hello, Kang-Oh Lee! Thank you for your valuable review! I made it so that even beginners to coding tests can listen to it without difficulty, including lecture materials and basic content, so I think you liked that part. ใ ใ It is an introductory lecture, but if you listen to the latter half of the lecture, I think it will be a lecture that is sufficient for passing the coding test! As you said, I will also review the problem-solving and advanced sections. If you have any questions while listening to the lecture, feel free to ask! Fighting until the end. :)

This is the best coding test lecture! I've only gotten to about 25% of the course, but I really like how it presents specific methods to improve my skills. I'm currently taking Essential Algorithm 1, and I'm confident that I can conquer the coding test if I follow the instructor's lectures. I'm going to run with the goal of completing the course this year! The detailed answers to my questions were also very helpful. I want to thank the instructor for creating such a high-quality lecture!!
Taejin Kim, hello! Thank you for your valuable course review. I am happy that I can provide you with specific help in improving your skills through the course. I believe that you will be able to achieve your goal of completing the course within this year, as I see that you are diligently following the Essential Algorithm 1 course. Feel free to ask questions at any time and I will do my best to answer them, so I hope you keep fighting until the end! I will cheer you on. Thank you!

Hello, Osoyoung! Thank you for your sincere review! You have organized the problem-solving video in a format that calculates the time complexity and derives the solution for the problem-solving, and you have pointed it out exactly. Based on what you said in the review, it seems like you are studying in the right direction! Fighting until the end :)

Hello, Mr. Kim Gyu-hyeok! Thank you so much for your sincere review. It may be difficult to understand the relationship between for loops and recursive functions in combination algorithms at first, so I'm glad that it helped you. ใ ใ Recursive functions are a difficult concept to approach at first, but once you understand them correctly, they are powerful tools that can be applied to various problems. I hope you continue to study hard, and if you have any questions or concerns, please feel free to contact me. Thank you :)
