--- Day 17: Pyroclastic Flow ---
|
||||
|
||||
Your handheld device has located an alternative exit from the cave for you and the elephants. The ground is
|
||||
rumbling almost continuously now, but the strange valves bought you some time. It's definitely getting warmer in
|
||||
here, though.
|
||||
|
||||
The tunnels eventually open into a very tall, narrow chamber. Large, oddly-shaped rocks are falling into the
|
||||
chamber from above, presumably due to all the rumbling. If you can't work out where the rocks will fall next, you
|
||||
might be crushed!
|
||||
|
||||
The five types of rocks have the following peculiar shapes, where # is rock and . is empty space:
|
||||
|
||||
####
|
||||
|
||||
.#.
|
||||
###
|
||||
.#.
|
||||
|
||||
..#
|
||||
..#
|
||||
###
|
||||
|
||||
#
|
||||
#
|
||||
#
|
||||
#
|
||||
|
||||
##
|
||||
##
|
||||
|
||||
The rocks fall in the order shown above: first the - shape, then the + shape, and so on. Once the end of the list
|
||||
is reached, the same order repeats: the - shape falls first, sixth, 11th, 16th, etc.
|
||||
|
||||
The rocks don't spin, but they do get pushed around by jets of hot gas coming out of the walls themselves. A quick
|
||||
scan reveals the effect the jets of hot gas will have on the rocks as they fall (your puzzle input).
|
||||
|
||||
For example, suppose this was the jet pattern in your cave:
|
||||
|
||||
>>><<><>><<<>><>>><<<>>><<<><<<>><>><<>>
|
||||
|
||||
In jet patterns, < means a push to the left, while > means a push to the right. The pattern above means that the
|
||||
jets will push a falling rock right, then right, then right, then left, then left, then right, and so on. If the
|
||||
end of the list is reached, it repeats.
|
||||
|
||||
The tall, vertical chamber is exactly seven units wide. Each rock appears so that its left edge is two units away
|
||||
from the left wall and its bottom edge is three units above the highest rock in the room (or the floor, if there
|
||||
isn't one).
|
||||
|
||||
After a rock appears, it alternates between being pushed by a jet of hot gas one unit (in the direction indicated
|
||||
by the next symbol in the jet pattern) and then falling one unit down. If any movement would cause any part of the
|
||||
rock to move into the walls, floor, or a stopped rock, the movement instead does not occur. If a downward movement
|
||||
would have caused a falling rock to move into the floor or an already-fallen rock, the falling rock stops where it
|
||||
is (having landed on something) and a new rock immediately begins falling.
|
||||
|
||||
Drawing falling rocks with @ and stopped rocks with #, the jet pattern in the example above manifests as follows:
|
||||
|
||||
The first rock begins falling:

To prove to the elephants your simulation is accurate, they want to know how tall the tower will get after 2022
|
||||
rocks have stopped (but before the 2023rd rock begins falling). In this example, the tower of rocks will be 3068
|
||||
units tall.
|
||||
|
||||
How many units tall will the tower of rocks be after 2022 rocks have stopped falling?
|
||||

--- Day 19: Not Enough Minerals ---
|
||||
|
||||
Your scans show that the lava did indeed form obsidian!
|
||||
|
||||
The wind has changed direction enough to stop sending lava droplets toward you, so you and the elephants exit
|
||||
the cave. As you do, you notice a collection of geodes around the pond. Perhaps you could use the obsidian to
|
||||
create some geode-cracking robots and break them open?
|
||||
|
||||
To collect the obsidian from the bottom of the pond, you'll need waterproof obsidian-collecting robots.
|
||||
Fortunately, there is an abundant amount of clay nearby that you can use to make them waterproof.
|
||||
|
||||
In order to harvest the clay, you'll need special-purpose clay-collecting robots. To make any type of robot,
|
||||
you'll need ore, which is also plentiful but in the opposite direction from the clay.
|
||||
|
||||
Collecting ore requires ore-collecting robots with big drills. Fortunately, you have exactly one ore-collecting
|
||||
robot in your pack that you can use to kickstart the whole operation.
|
||||
|
||||
Each robot can collect 1 of its resource type per minute. It also takes one minute for the robot factory (also
|
||||
conveniently from your pack) to construct any type of robot, although it consumes the necessary resources
|
||||
available when construction begins.
|
||||
|
||||
The robot factory has many blueprints (your puzzle input) you can choose from, but once you've configured it
|
||||
with a blueprint, you can't change it. You'll need to work out which blueprint is best.
|
||||
|
||||
For example:
|
||||
|
||||
Blueprint 1:
|
||||
Each ore robot costs 4 ore.
|
||||
Each clay robot costs 2 ore.
|
||||
Each obsidian robot costs 3 ore and 14 clay.
|
||||
Each geode robot costs 2 ore and 7 obsidian.
|
||||
|
||||
Blueprint 2:
|
||||
Each ore robot costs 2 ore.
|
||||
Each clay robot costs 3 ore.
|
||||
Each obsidian robot costs 3 ore and 8 clay.
|
||||
Each geode robot costs 3 ore and 12 obsidian.
|
||||
|
||||
(Blueprints have been line-wrapped here for legibility. The robot factory's actual assortment of blueprints are
|
||||
provided one blueprint per line.)
|
||||
|
||||
The elephants are starting to look hungry, so you shouldn't take too long; you need to figure out which
|
||||
blueprint would maximize the number of opened geodes after 24 minutes by figuring out which robots to build and
|
||||
when to build them.
|
||||
|
||||
Using blueprint 1 in the example above, the largest number of geodes you could open in 24 minutes is 9. One way
|
||||
to achieve that is:
|
||||
|
||||
== Minute 1 ==
|
||||

2 geode-cracking robots crack 2 geodes; you now have 9 open geodes.
|

|

However, by using blueprint 2 in the example above, you could do even better: the largest number of geodes you
|
||||
could open in 24 minutes is 12.
|
||||
|
||||
Determine the quality level of each blueprint by multiplying that blueprint's ID number with the largest number
|
||||
of geodes that can be opened in 24 minutes using that blueprint. In this example, the first blueprint has ID 1
|
||||
and can open 9 geodes, so its quality level is 9. The second blueprint has ID 2 and can open 12 geodes, so its
|
||||
quality level is 24. Finally, if you add up the quality levels of all of the blueprints in the list, you get
|
||||
33.
|
||||
|
||||
Determine the quality level of each blueprint using the largest number of geodes it could produce in 24
|
||||
minutes. What do you get if you add up the quality level of all of the blueprints in your list?
