Tried that and don't know how I successfully studied computer science that way. I could reproduce solutions, but I never understood them. Years after I saw a bunch of good practicable examples and I just understood what the concept was about. After this realization, I refined my learning approach. 1. Fly over the core concepts. 2. Try a bunch of examples until I understand why I would need the concept. 3. Read the core concept thoroughly to eliminate the edge cases that are missing in the naive examples.
