Data Structures and Algorithms Explained Simply with Pictures (Advanced)

It's been a while since I bought it, but I finally finished it once.. Following the linear data structure (basic), the lecture on nonlinear data structure (advanced) was also explained very well, so it helped me a lot to clarify the concepts of tree and graph data structures that I had previously learned sporadically. I think the episode related to the XOR operation was the most memorable. Thanks to this, I think I won't be confused either ㅋㅋ (If the input value is odd, it's 1..) I will listen to the lecture repeatedly in the future and become a developer who is more faithful to the basics :) Thank you for the great lecture, and I look forward to the next lecture!

Yay~! @#$%^&*() I finally broke a jinx. (Self-help/knowledge and repeat the cycle) When I studied from a book all the time, from about the middle of the tree, I would close the book and after a few months, [Initialize > Review] would repeat endlesslyㅠ Of course, there were parts I didn't understand in the logic (implementation), but for the first time, I organized the concepts for topics that came out from the beginning to the end. (No memorization) And I think I felt a little bit why there are algorithms in computer science subjects. Thank you, Mr. Potato! [Recommended parts] 1. The structure that goes beyond each data structure was delivered in a storytelling style, so it didn't have to be memorized, but it came to me naturally, which helped me a lot in continuing the progress. 2. When I looked at the book, there were many times when I didn't know which part was the important point, but it was good that the important points were emphasized and repeated. Ex) When studying the concept of recursion in the old algorithm, I just said, "Function calls itself and ends (thinking only technically)" I had skipped over it, but While listening to the lecture, the concept of recursion was used algorithmically (it was hard to express), and I was surprised, thinking, "Oh, this isn't the recursion I knew?" 3. Only the core parts were summarized, so the amount was appropriate, and almost all parts (even in the implementation) were visualized, so it was definitely easy to understand. I recommend it to those who are studying data structures/algorithms for the first time or want to quickly organize before an interview. ps) I'm being cautious, but If there's anyone who feels depressed because they don't understand the logic part, there's no need to be. Most people seem to find it difficult and complicated. First, I recommend that you grasp the big picture of each topic's concept and study it repeatedly when you have time. [Regrettable parts] 1. Personally, after finishing the two lectures on the concept of red-black trees (insertion/removal), I only had question marks in my head. After looking at the concept part of other data structures, I had a rough idea of what they would look like, but the Red-Black Tree was just a question mark. ㅠ ps: After researching separately, I came up with a very rough idea. - While making meat (black) and vegetable (red) fried rice, the assistant chef keeps putting vegetables on one side and mixing them again. - On the Earth, which is made up of oxygen (black) and carbon dioxide (red), carbon dioxide keeps coming down toward a certain country and dispersing to other countries. And AVL trees are a situation where gears mesh together and are precisely balanced. 2. I think the version with background music is better because it feels like watching a science YouTube.

I was learning various data structures and solving algorithm problems at the same time, and I think it was definitely helpful. Even if I don't use it directly, it helped me a lot in terms of depth and breadth of thinking, and how to approach algorithm problems, so I think it was a good idea to listen to it. It was easy to understand because it was explained step by step with pictures. I was satisfied with the basics, so I listened to the advanced version, and I think it was a really good choice. Thank you!! :)

I think it's really easy to understand when you show the structure of the implementation in a diagram. It was really helpful.

Since Lydia Harley of Vercel, this person seems to be the only one who can do code visualizations of this quality.

The course structure is systematic and the examples are appropriate, which helps build a solid foundation.

Thank you for the precious lecture.

It was a difficult lecture, but thanks to it, I think I was able to do it easily.
