Challenge 28 Marked

Congrats to Pedro Graca who once again wins though the competition was out of sight this time. His C entry calculated the puzzle answer in about 3 seconds and though it didn't create a valid CSV file, it would be churlish not to cite him as the winner.

I've had the first entry for Challenge 29 from John Downey of Purdue University. Starting from this weekend, I'll try and mark these as they come in but no source code will be published until the challenge ends.
