Think of the simplest version of the problem that isn't totally trivial. e.g. A one dimensional list of numbers. What would you do? Note: you only want to touch each element once. The 2 dimensional case could be handled by putting into lists: rows, columns, major diagonals, and minor diagonals. This isn't the fastest way of doing the problem but it has the advantage of avoiding "indexitis". On Fri, Aug 26, 2011 at 6:15 PM, Oscar Picasso wrote:

Like: 20*19*21*18 is bigger than 100*100*3*2 ?

If so I need to think about how to formalize it.

Thanks for the hint.

Is Problem 11 the 4 consecutive #'s problem?

If so what must be true for 4 #'s to have a large product?

Hint: x * y * z * 2 is that going to be larger?
