I just started DingCodingKo classes and it's still early, but I've noticed some advantages that are different from previous classes. I had taken classes from other instructors to prepare for coding tests, but I felt that I lacked a deep understanding of problem approaches and algorithms. Then I came across the DingCodingKo channel and decided to take the class because of the systematic and friendly class structure. Even though I'm still early in the class, I've definitely noticed the strengths of DingCodingKo classes. 1. Easy to understand explanations: The use of visual materials and real-life analogies to help easily understand complex algorithm concepts is really helpful. 2. Logical thinking training: Rather than simply following the solution process, it gradually teaches you how to approach and think about problems, making it suitable for building a foundation. 3. Cultivating practical skills: I liked the structure that covers types of problems that frequently appear in actual coding tests and efficient solutions from the beginning of the class.
