Algorithm Coding Test to Pass in 2 Weeks (2024)

Isn't it fun?

I don't know how old you are when you read this lecture, but When I was young, there was a program about a painter named Bob Ross who drew amazing pictures. The painter and the instructor are very similar. The painter draws ridiculous pictures quickly and says, "It's easy, right?" The instructor of this lecture also codes and explains in detail in each lecture and says, "It's easy, right?" But it's not easy if I do it... Don't be fooled by the instructor. It's not easy. It's difficult. The only hope is that he explains it well. If other people's lectures are like Leonardo da Vinci's paintings and you have to just look at them, this lecture is like Bob Ross's paintings and you can follow along at first. I don't think there's an easier lecture than this for a beginner who just finished learning Python grammar.

My current status is that I have learned Java and only learned Python grammar from a book for the coding test. I have recently taken the coding test a few times, so I have not listened to all the lectures, but I have listened to half of them, and I am leaving a review after repeating them 2-3 times. Advantages 1. I learned that I can solve the coding test this way (thought) I had never thought of solving it with an exhaustive search before, but now that I know that I can solve it this way, I am able to solve it better. 2. I can solve some bronze problems and some silver problems. Before, I could only solve problems that I knew the real grammar, but now that I have solved some silver problems, I feel like I have grown a little. 3. If you understand it, you will gain powerful tools. If you understand it 100%, you will gain a strong weapon to deal with the enemy called the coding test. Disadvantages 1. You may have to repeat it more than 3 times to understand it. (This is my subjective standard.) I forgot which lecture it was, but after watching it more than 3-4 times, I was able to understand that part. (But there are times when I forget againㅋㅋㅋㅋ) 2. It can be difficult for beginners. It was difficult to understand from my perspective. (Coding Sensei said it was easy, but from my perspective, there were many times when I didn't understand it..ㅠㅠㅠ I don't mean to criticize.) I think it would be good to solve Python grammar + 100 basic Python problems before listening to this. I'm sure that it wouldn't be a loss to buy it at this price and this level of quality.

This is a lecture that teaches you how to come up with ideas by understanding the algorithm rather than focusing only on solving problems. I realized right away that I had been studying incorrectly up until now. This is a lecture worth listening to at least once for everyone who has difficulty with coding tests.

In my case, I have some basic skills and I play PS as a hobby. I gained insight by solving 300~400 problems on Baekjoon Corpo, etc., namely, the way computers think, why did they solve it with this algorithm? This way of thinking and system is explained from the first lecture. It was interesting that it was not a lecture that just explained the algorithm and solved the problem.

The reason why this lecture is good is for those who have given up on algorithms 1. It tries to teach algorithms that are easy to understand, not memorization-based 2. It tries to make algorithms fun to understand 3. It is not something that can be easily understood, but "Forcing people to understand"..? "Emphasizing that it is easy..?" It was a bit of a strange lecture. I think it wasn't very helpful because there was a lot of content that I already knew, but it was a lecture that made me understand the intentions of the lecture creator. Regardless of the quality of the lecture, I wish there were more algorithm lectures that focus on understanding like this.

Wow.. I was really amazed while taking this class. Usually, when preparing for the coding test, I thought a lot, 'Oh, how should I approach this?', 'Do I have no talent?'. Even before taking this class, I was hesitant and watched the preview. After watching the preview, I thought, 'Should I listen to it?' While taking the class, I listened to each lecture, and not only did I understand the algorithm, but the optimization method was so perfect in the introduction, development, climax, and conclusion. Every time I listened, I thought, 'This is really a great lecture' and recommended it to my schoolmates. This price might be a waste for some, but I strongly recommend that you take Coding Sensei's class without eating a pizza. I recommend it once again to those who, like me, are at a loss and frustrated from the beginning. I now understand why this problem should be approached this way and why this algorithm is suitable. Coding Sensei, thank you so much. I will approach problems with a coding-sensory mindset in the future. I would appreciate it if you could continue to make lectures like this in the future. Be happy!!! P.S. The lectures are really funnyㅋㅋㅋㅋㅋㅋㅋ Isn't it fun? ㅎㅎ

After studying algorithms that are solved by memorization, I finally feel like I understand what an algorithm is because I studied algorithms that are solved by understanding. I thought that exhaustive search meant just easy problems in the beginning, but it wasn't like that. I was impressed by the statement, "All problems can be solved by exhaustive search, and the process of optimizing that is an algorithm."
