Is the adventofcode.com fun/educational/worthwhile? I see it starts again Dec 1. I like doing things like this but end up regretting it as it sucks too much time solving unnecessary problems.
Well I would consider any puzzle type problems technically "unnecessary" but I thought the adventofcode puzzles in 2016 were fun, well designed and tapped into some good CS algorithm and theory stuff.
I imagine the best way to make it educational would be to skip the problems you know how to solve and then try to solve the others without a whole lot of "cheating".
Obviously looking at resources to learn approaches to solving the problem isn't cheating, but there is some value in spending time just trying to figure out an approach before doing that.
