Leaderboard Positions - Part 1: 1835, Part 2: 609
Hello all! In this puzzle, we are find different instructions in a block of characters. In part 1, we are finding all the mul
instructions with proper formatting (ex: mul(a, b), with a and b being numbers). I used a regular expression with two capture
groups to find all mul strings, then add all the results to return the answer. In part 2, we must now also account for do() and don't(), which either allows or disallows the mul instruction. Again, I used a regex that also checks
for the new instructions. I used a .matchAll(), which allows the regex to go in order. I have a flag that toggles between adding
and not adding.
