in thread Challenge: Number of unique ways to reach target sum
Quite impressive. It does not come near to being what I had hoped for but that is my fault. I was so close to the problem that I could not see the forest through the trees. I naively assumed that counting the ways would mean generating them and as you and others have shown - this is a very poor assumption.
I am very happy that you have contributed though because not only do I know a little bit more about math theory, I have a new way of looking at problems.
