Introduction to Java Algorithm Problem Solving: Coding Test Preparation

I am not a major, but I always felt scared because I thought that data structures, algorithms, and coding tests were difficult subjects for majors. However, in order to get a job, I had to study in the end... So while looking for a lecture, I ended up taking the instructor's lecture. The conclusion is very satisfying. I had to memorize the problems because my skills were lacking, but thanks to the instructor, I was able to study a lot about algorithms and data structures that were unfamiliar to me. What I was particularly satisfied with in the lecture was that even a beginner like me could understand it very well by drawing pictures and explaining how they worked. And I often thought that I lacked the "problem-solving skills" that are necessary for programmers because I couldn't solve those problems at the academy... or that I didn't have the qualities of a developer... but the instructor told me to just memorize the basic algorithms here and there, which was a great comfort. I gained hope that even good people have to memorize the basics... and that problem-solving skills are not innate but are developed. So even if I can't solve the problem right now, I'm just going to memorize the basic algorithms! I've talked too long. For those of you who are non-majors like me and want to get a job at a good company, I highly recommend this course. Don't hesitate and take it! :)

This is the best algorithm lecture. I only took this lecture and passed most of the coding test. (Except for the difficult parts) It would be good if there was a next level lecture... Since you taught me how to hold a spoon, I guess I should eat on my own now?ㅠ

This is what I felt after completing the course. I really recommend it to those who are starting to learn algorithms in Java. At first, I was worried that the lecture quality would be poor because the price was cheaper than other algorithm lectures, but the lecture was very easy to understand and good because the teacher's interesting way of speaking and the lecture followed each index. (Especially DFS and BFS are great lectures) And it was too hard when I tried to study from a book, but I think online lectures are good when learning other people's solutions. I wish the teacher would publish an intermediate version of Java algorithms.

I am a career developer. I was studying alone because my coding test skills were lacking, but I found this lecture while looking for one. The conclusion is really satisfying. Since you explain code debugging with pictures, even beginners can understand it well! If there is something a little disappointing, It would be good to explain it by drawing it in real time, but it would be cleaner if you made it into materials in advance and used it. And it would be better if you drew it with a drawing pad or something!

This is a really good lecture for beginners in algorithms. I read the reviews before taking the lecture, but since they are subjective, they may differ, but you don't need to refer to the reviews with low stars. They say that it is insincere to draw and explain with a drawing program, but if you take the lecture yourself, there will be no problem at all. The instructor repeatedly explains it in an easy way so that even beginners can understand, so I recommend it to beginners in algorithms.

I've been studying algorithms on my own. I just solved them step by step on Baekjoon, so I just did that, but after about 3 months, I felt hopeless at the recursion part. I was frustrated because I was not smart enough, but luckily I came across this lecture. I was originally listening to lectures on other sites besides Inflearn. When I looked at the lecture list, it wasn't about algorithm theory, but lectures that taught how to solve problems. I thought, "Oh, this is it," and opened an online study group and set a goal of solving 2 problems a day. When I solved problems on my own on Baekjoon, there were many times when I doubted whether this was the right way to solve the problems. There are better algorithms for some problems, but I solved them with recursion and ran out of time... It would be better if I could do it, but if I couldn't, I just passed. But this lecture gave me good directions, so I could see if I was on the right path. I really enjoyed it for 6 weeks. Thank you!

It was tough. Even if you look around here and there to study algorithms, most of them just throw out code and tell you to figure it out and eat it. It would be great if they even gave you code. This lecture explains in detail the process of each index entering and leaving memory. Even if it seems hard to understand at first, after listening to the explanation a few times and solving a few similar example problems, there will be a moment when you really understand it. I really recommend it. I really hope they give you an intermediate version.

I started off worried because there was a bad story at the top of the course review. At first, I didn't know anything about algorithms, so my goal was to improve my skills quickly, and I was worried because the lectures were long. After watching it all, I think that I can learn more in a shorter period of time by following the organized lectures rather than studying on my own. It was good because they explained the basics and debugging, and since it was a basic algorithm, I just memorized the parts that I needed to memorize. And a tip for those who found the lecture speed frustrating!!! It's good to watch at 1.25x speed!!
