It's time to take a look at the parts I'm not familiar with.

This is a great lecture for building coding test fundamentals. I took advanced studies with leetcode while attending this lecture, and learning the basics through the lecture first rather than just solving problems randomly was much more effective for problem-solving! I recommend this lecture to algorithm beginners.

I didn't solve all problems during the lectures; my progress is low, but I'm on Section 8. Lectures are good, but I recommend it as I gain much from reviewing problems on essential topics and their solution codes. I hesitated to buy this lecture due to no grading site, but it's less inconvenient than expected. Still, having one would've been better.

Thanks to the instructor, my problem-solving thinking is expanding, so I'm writing this course review with a grateful heart. I wanted to change jobs, so I solved a lot of basic coding test problems, but moving beyond the basic level still feels too difficult, and because it's hard, I didn't want to do it anymore, so I was a developer suffering from pain.. ^^ Recently, I've been listening to the instructor's lectures step by step, and solutions that couldn't come from my head are presented with easy-to-understand explanations, so I think 'Wow.. are you a genius..?' during every lecture. I looked at problems and first thought of data structures like hashmaps, then watched the lectures in a state of confusion about how to solve them, but I was shocked to see that in the lectures, problems were solved with just for loops and if statements, and I really felt the aura of a master.. I'm learning a lot.

Makes it very clear.
