Thank you for providing such excellent lectures. The quality of the course materials was particularly high and very helpful. It included not only algorithms but also fundamental concepts like array rotation, split function implementation, and the Sieve of Eratosthenes, which made it much easier to understand. Also, by repeatedly solving the problems you recommended on Baekjoon, I was able to build my skills, and thanks to this, I was able to pass the Toss coding test. I sincerely thank you.
