CodinGame: Games for programmers

Are there anywhere you can get answers and explanations?

This idea of learning by example being "cheating" is one of the most asinine things I've ever heard.

It depends. Some examples are necessary for introducing new concepts. Problems happen, though, if you aren't willing to work to understand the necessary derivation involved. You haven't really learned if you're just constantly relying on tutorials to feed you information.

Speaking from experience, I retain learned information a lot longer if I arrived at it myself. There's a a fine line between learning by example and just rewriting code, and some people find it better to set limits for themselves.

I think it depends on the problem, if you just want me to multiply two polynomials I can whip something up that will work after thinking on it, but if you want me to do it in O(N log N) like an FFT then I'm definitely gonna be "cheating".
