Heybob's algorithm lectures are special because their purpose is clear. It feels like a 1:1 tutoring session, and it's made with an essential understanding of what a "major company coding test" is. With Heybob's own outstanding learning ability and mathematical knowledge (you will agree with this after listening to Heybob's YouTube videos and lectures), you can learn the algorithm problem-solving approach and solutions that he has already mastered, like receiving 1:1 tutoring, with only the essential information remaining. Each chapter is divided into very well-organized, easily digestible amounts, and the conceptual explanations are also presented in a concise, list-like format with a very restrained feel. Examples written and drawn directly in a nice handwriting style are very effective in understanding concepts, thinking methods, and problem-solving. Each chapter provides basic mathematical concepts needed, selected problems with step-by-step difficulty that you can solve on your own, and target problems. The accessibility is good because you can write and run code directly in your web browser without having to download anything. To me, Heybob's lecture feels like a "master's secret" that is worth listening to repeatedly, not just once. Thank you for creating such a great lecture. It was one of the few channels I subscribed to and set up notifications for since the YouTube days, and the lecture was much more satisfying than I expected when you said you were making it. Finally, I'd like to share some of the expressions/explanations/advice from Heybob's lectures that resonated with me. Study method: "If you don't know the principles and basics, there will be too many things to study." "You have to memorize the basics." "You have to be able to solve the examples, and you have to understand how you solved them through metacognition." Coding concept: "Data must be organized in a specific way to implement a specific function." "The most important thing is to impose restrictions so that the data I create can be used safely." "Recurrence relation: a machine that derives the current term result from the previous term value." "What is a non-linear data structure? Cannot be traversed with a loop. It is unclear where to go in the next order." Edit: Typos corrected.
