bah, my lack of knowledge of probability fails me again
A very interesting probability problem applicable across a lot of areas underlies the solution. It isn't obvious at first glance. The solution is fairly short, but it takes a lot of thought to get it. I can't wait to see the length 14 solution!
ironic solution ftw!
I should have known! :) Next problem is, how many times can you expect to submit that solution! :)
OK. You've gamed the solution. The author shouldn't have to beef up the test suite to prevent this sort of solution.
