+
+--- Day 16: Proboscidea Volcanium ---
+
+   The sensors have led you to the origin of the distress signal: yet another handheld device, just like the one the Elves
+   gave you. However, you don't see any Elves around; instead, the device is surrounded by elephants! They must have gotten
+   lost in these tunnels, and one of the elephants apparently figured out how to turn on the distress signal.
+
+   The ground rumbles again, much stronger this time. What kind of cave is this, exactly? You scan the cave with your
+   handheld device; it reports mostly igneous rock, some ash, pockets of pressurized gas, magma... this isn't just a cave,
+   it's a volcano!
+
+   You need to get the elephants out of here, quickly. Your device estimates that you have 30 minutes before the volcano
+   erupts, so you don't have time to go back out the way you came in.
+
+   You scan the cave for other options and discover a network of pipes and pressure-release valves. You aren't sure how
+   such a system got into a volcano, but you don't have time to complain; your device produces a report (your puzzle input)
+   of each valve's flow rate if it were opened (in pressure per minute) and the tunnels you could use to move between the
+   valves.
+
+   There's even a valve in the room you and the elephants are currently standing in labeled AA. You estimate it will take
+   you one minute to open a single valve and one minute to follow any tunnel from one valve to another. What is the most
+   pressure you could release?
+
+   For example, suppose you had the following scan output:
+
+ Valve AA has flow rate=0; tunnels lead to valves DD, II, BB
+ Valve BB has flow rate=13; tunnels lead to valves CC, AA
+ Valve CC has flow rate=2; tunnels lead to valves DD, BB
+ Valve DD has flow rate=20; tunnels lead to valves CC, AA, EE
+ Valve EE has flow rate=3; tunnels lead to valves FF, DD
+ Valve FF has flow rate=0; tunnels lead to valves EE, GG
+ Valve GG has flow rate=0; tunnels lead to valves FF, HH
+ Valve HH has flow rate=22; tunnel leads to valve GG
+ Valve II has flow rate=0; tunnels lead to valves AA, JJ
+ Valve JJ has flow rate=21; tunnel leads to valve II
+
+   All of the valves begin closed. You start at valve AA, but it must be damaged or jammed or something: its flow rate is
+   0, so there's no point in opening it. However, you could spend one minute moving to valve BB and another minute opening
+   it; doing so would release pressure during the remaining 28 minutes at a flow rate of 13, a total eventual pressure
+   release of 28 * 13 = 364. Then, you could spend your third minute moving to valve CC and your fourth minute opening it,
+   providing an additional 26 minutes of eventual pressure release at a flow rate of 2, or 52 total pressure released by
+   valve CC.
+
+   Making your way through the tunnels like this, you could probably open many or all of the valves by the time 30 minutes
+   have elapsed. However, you need to release as much pressure as possible, so you'll need to be methodical. Instead,
+   consider this approach:
+
+ == Minute 1 ==
+ No valves are open.
+ You move to valve DD.
+
+ == Minute 2 ==
+ No valves are open.
+ You open valve DD.
+
+ == Minute 3 ==
+ Valve DD is open, releasing 20 pressure.
+ You move to valve CC.
+
+ == Minute 4 ==
+ Valve DD is open, releasing 20 pressure.
+ You move to valve BB.
+
+ == Minute 5 ==
+ Valve DD is open, releasing 20 pressure.
+ You open valve BB.
+
+ == Minute 6 ==
+ Valves BB and DD are open, releasing 33 pressure.
+ You move to valve AA.
+
+ == Minute 7 ==
+ Valves BB and DD are open, releasing 33 pressure.
+ You move to valve II.
+
+ == Minute 8 ==
+ Valves BB and DD are open, releasing 33 pressure.
+ You move to valve JJ.
+
+ == Minute 9 ==
+ Valves BB and DD are open, releasing 33 pressure.
+ You open valve JJ.
+
+ == Minute 10 ==
+ Valves BB, DD, and JJ are open, releasing 54 pressure.
+ You move to valve II.
+
+ == Minute 11 ==
+ Valves BB, DD, and JJ are open, releasing 54 pressure.
+ You move to valve AA.
+
+ == Minute 12 ==
+ Valves BB, DD, and JJ are open, releasing 54 pressure.
+ You move to valve DD.
+
+ == Minute 13 ==
+ Valves BB, DD, and JJ are open, releasing 54 pressure.
+ You move to valve EE.
+
+ == Minute 14 ==
+ Valves BB, DD, and JJ are open, releasing 54 pressure.
+ You move to valve FF.
+
+ == Minute 15 ==
+ Valves BB, DD, and JJ are open, releasing 54 pressure.
+ You move to valve GG.
+
+ == Minute 16 ==
+ Valves BB, DD, and JJ are open, releasing 54 pressure.
+ You move to valve HH.
+
+ == Minute 17 ==
+ Valves BB, DD, and JJ are open, releasing 54 pressure.
+ You open valve HH.
+
+ == Minute 18 ==
+ Valves BB, DD, HH, and JJ are open, releasing 76 pressure.
+ You move to valve GG.
+
+ == Minute 19 ==
+ Valves BB, DD, HH, and JJ are open, releasing 76 pressure.
+ You move to valve FF.
+
+ == Minute 20 ==
+ Valves BB, DD, HH, and JJ are open, releasing 76 pressure.
+ You move to valve EE.
+
+ == Minute 21 ==
+ Valves BB, DD, HH, and JJ are open, releasing 76 pressure.
+ You open valve EE.
+
+ == Minute 22 ==
+ Valves BB, DD, EE, HH, and JJ are open, releasing 79 pressure.
+ You move to valve DD.
+
+ == Minute 23 ==
+ Valves BB, DD, EE, HH, and JJ are open, releasing 79 pressure.
+ You move to valve CC.
+
+ == Minute 24 ==
+ Valves BB, DD, EE, HH, and JJ are open, releasing 79 pressure.
+ You open valve CC.
+
+ == Minute 25 ==
+ Valves BB, CC, DD, EE, HH, and JJ are open, releasing 81 pressure.
+
+ == Minute 26 ==
+ Valves BB, CC, DD, EE, HH, and JJ are open, releasing 81 pressure.
+
+ == Minute 27 ==
+ Valves BB, CC, DD, EE, HH, and JJ are open, releasing 81 pressure.
+
+ == Minute 28 ==
+ Valves BB, CC, DD, EE, HH, and JJ are open, releasing 81 pressure.
+
+ == Minute 29 ==
+ Valves BB, CC, DD, EE, HH, and JJ are open, releasing 81 pressure.
+
+ == Minute 30 ==
+ Valves BB, CC, DD, EE, HH, and JJ are open, releasing 81 pressure.
+
+   This approach lets you release the most pressure possible in 30 minutes with this valve layout, 1651.
+
+   Work out the steps to release the most pressure in 30 minutes. What is the most pressure you can release?
+
+   To begin, get your puzzle input.
