One new thought for this discussion.
I changed from rep in 3 to rep in 2, and my program got a lot faster!(also the
cache should recognize the repetition?) If I find repetition, I stop the search
and return 0. 0 scores, I never put into Hashtables.
On the other hand, you are true with your irregular examples.
It is difficult to say, which thing is better.
