Struct year2016::Day12

pub struct Day12 { /* private fields */ }

2016 Day 12: Interpreting assembly, again.

The key optimization is that

inc $r1
dec $r2
jnz $r2 -2

can be replaced with $r1 += $r2 followed by $r2 = 0. This reduces the number of simulated cycles ~5,000 times for part 1 and ~100,000 times for part 2, to around ~200 cycles each.
