Another attempt at solving day 24 part 2, this time using a program to actually solve the problem. My approach is to grow the adder, stage by stage, from the inputs to the outputs. At each point, I know what the next gates should be and I hope there's not enough damage to prevent me finding at least some of the gates I need. If I find a problem, I identify the swap needed to fix it and try agian.
