Day 12

See details of the challenge here.

The input for today’s challenge looks like this:

cpy 1 a
cpy 1 b
cpy 26 d
jnz c 2
jnz 1 5
cpy 7 c

This is very similar to Day 23 of Advent of Code 2015 and looking at my solution then I thought I could simplify it slightly this time around.

 

Part 2

As you head down the fire escape to the monorail, you notice it didn’t start;
register c needs to be initialized to the position of the ignition key.

If you instead initialize register c to be 1, what value is now left in register a?

because of the work we did in part 1, part 2 is a simple one liner:

let part2 = (execute [ “c”, 1 ] inputs).[“a”]
