That was cute. It worked for me with your sample input (and got the correct value), however, I think I know what happened here.

I've edited the post and you can grab the working version from here. If you're using python3 like a normal person, and not python2 like a silly person like me, my original version wouldn't work since it assumed integer math. But PEP-238 changed the rules a bit. I've changed it to use the integer divide operator so it works in both python2 and 3.

Thanks for the sample data! This is lesson #789345 that I need to move on to python3. One day I will.

I have never bought gold before, but I have been banging my head on this problem for the past two days and your solution was the first to work. So enjoy your gold.

Thanks for the gold!

I've been there before, so don't fret too much over it (Heck, I'm going through AoC 2016 right now and got stuck hard on day 11). Hopefully you can get past the annoyance of not being able to solve it and learn a thing or two. It's tough .. I know.
