I'm trying to study algorithms properly, so I'm taking a lecture that focuses on concepts and is aimed at beginners, but it's not a lie, it gets harder as it goes on. The explanations are poor, so I don't understand, but I just do it, solve it, and it's over. Is this the right way...? There were many times when I didn't understand the lecture and used other blogs or GPT to understand it. It feels like that's more helpful than taking this lecture.
