--- Part Two ---
As soon as people start to arrive, you realize your mistake. People don't just care about adjacent
seats - they care about [1m[37mthe first seat they can see[0m in each of those eight directions!
Now, instead of considering just the eight immediately adjacent seats, consider the [1m[37mfirst
seat[0m in each of those eight directions. For example, the empty seat below would see
[1m[37meight[0m occupied seats:
.......#. ...#..... .#....... ......... ..#L....# ....#.... ......... #........ ...#.....
The leftmost empty seat below would only see [1m[37mone[0m empty seat, but cannot see any of the
occupied ones:
............. .L.L.#.#.#.#. .............
The empty seat below would see [1m[37mno[0m occupied seats:
.##.##. #.#.#.# ##...## ...L... ##...## #.#.#.# .##.##.
Also, people seem to be more tolerant than you expected: it now takes [1m[37mfive or more[0m
visible occupied seats for an occupied seat to become empty (rather than [1m[37mfour or more[0m
from the previous rules). The other rules still apply: empty seats that see no occupied seats become
occupied, seats matching no rule don't change, and floor never changes.
Given the same starting layout as above, these new rules cause the seating area to shift around as
follows:
L.LL.LL.LL LLLLLLL.LL L.L.L..L.. LLLL.LL.LL L.LL.LL.LL L.LLLLL.LL ..L.L..... LLLLLLLLLL L.LLLLLL.L
L.LLLLL.LL
#.##.##.## #######.## #.#.#..#.. ####.##.## #.##.##.## #.#####.## ..#.#..... ########## #.######.#
#.#####.##
#.LL.LL.L# #LLLLLL.LL L.L.L..L.. LLLL.LL.LL L.LL.LL.LL L.LLLLL.LL ..L.L..... LLLLLLLLL# #.LLLLLL.L
#.LLLLL.L#
#.L#.##.L# #L#####.LL L.#.#..#.. ##L#.##.## #.##.#L.## #.#####.#L ..#.#..... LLL####LL# #.L#####.L
#.L####.L#
#.L#.L#.L# #LLLLLL.LL L.L.L..#.. ##LL.LL.L# L.LL.LL.L# #.LLLLL.LL ..L.L..... LLLLLLLLL# #.LLLLL#.L
#.L#LL#.L#
#.L#.L#.L# #LLLLLL.LL L.L.L..#.. ##L#.#L.L# L.L#.#L.L# #.L####.LL ..#.#..... LLL###LLL# #.LLLLL#.L
#.L#LL#.L#
#.L#.L#.L# #LLLLLL.LL L.L.L..#.. ##L#.#L.L# L.L#.LL.L# #.LLLL#.LL ..#.L..... LLL###LLL# #.LLLLL#.L
#.L#LL#.L#
Again, at this point, people stop shifting around and the seating area reaches equilibrium. Once
this occurs, you count [1m[37m26[0m occupied seats.
Given the new visibility method and the rule change for occupied seats becoming empty, once
equilibrium is reached, [1m[37mhow many seats end up occupied?[0m
