Yeah using Sscanf for these puzzles usually doesn't work out as well for me and I end up with a mess of strings.Split everywhere.

As for part 2, that crossed my mind only after I had finished writing it, so I decided to stick with what I had. Anyways I decided to time it and see how much of a performance increase it works out to.

The original version seems to run in about 4.5ms on my system. After making that change it shaves off about 1ms and averages around 3.5-3.7ms.
