This is a short update to my previous post where I will solve the second part. At the end, I will also include one-line solutions to the two problems, which really doesn't involve more than removal of unnecessary variable assignments. Revisiting part 1, here's the full solution that was written in that post (with a few less variable reassignments): numbers ← ⍎¨ ⊃ {(@\s≠⍵) ⊂ ⍵}¨ io:read "part01.txt" (a b) ← ⊂[0] numbers a ← ∧a b ← ∧b +/ | a - b Solution to part 2 Le...
