github.com/PuercoPop/advent-of-code/blob/… one question about using ⌿ to filter the 'rows' in a 2d matrix down to one. How do I extract the final row to a vector? ⊃ would get only the first element and ↑ would swap the axis but there would still be two. I used ∨⌿ as a work around but I'm guessing there is a more direct way?
