Related problem, but smaller, allowed for a brute force solution. Discovered flaw in thinking and in algorithm, adjusted implementation to account for expectation, and now have a working algorithm. Problem 67 is essentially the same as problem 18 but with a bigger triangle, thus making a brute force solution impossible.
