Multiplying numbers on horizontal, vertial, and diagonal lines
- by untwisted
I'm currently working on a project Euler problem (www.projecteuler.net) for fun but have hit a stumbling block. One of the problem provides a 20x20 grid of numbers and asks for the greatest product of 4 numbers on a straight line. This line can be either horizontal, vertical, or diagonal.
Using a procedural language I'd have no problem solving…
