 general shape of the graph and the places where it seemed off, but beyond that, it gave me a headache to try to
 identify what the configuration of the full adder should look like for each z wire.
 
-I ended up implementing [a solution by someone](https://www.reddit.com/r/adventofcode/comments/1hneuf0/comment/m41ms44/)

-(the author reported it taking 2.5 mins on their machine). More details are in the code.

 I suppose slogging through it was worth the insight into how mathematical addition works at the level of logical gates
 (you need a carry bit!), even if I didn't use that knowledge for the actual solution.
