Tweet The problem description is here, and click here to see all my other Euler solutions in F#.   This is a more difficult version of problem 82, and now you can move in all four directions! As before, we start by loading the input data into a 2D array: and initialize another matrix of the

Tweet The problem description is here, and click here to see all my other Euler solutions in F#.   This is a more difficult version of problem 81, but still, as you can’t move left so we can still optimize one column at a time. First, let’s read the input file into a 2D array:
