I think this is a great effort. Are you at beginner level or advanced? My nephew is currently learning to code and the book he is using is very much university level content (read: utter garbage), it goes as far as distinguishing "inner loops". Any developer knows that there is nothing special about an inner loop (besides O(N^2)) - it's nothing more than logical progression. I'm looking for something worthwhile for him to learn from.

I've saved these reviews and will be contemplating them for his education - it would help to know how far along you were when approaching them.
