--- Day 5: Supply Stacks ---
|
||||
|
||||
The expedition can depart as soon as the final supplies have been
|
||||
unloaded from the ships. Supplies are stored in stacks of marked crates,
|
||||
but because the needed supplies are buried under many other crates, the
|
||||
crates need to be rearranged.
|
||||
|
||||
The ship has a giant cargo crane capable of moving crates between
|
||||
stacks. To ensure none of the crates get crushed or fall over, the crane
|
||||
operator will rearrange them in a series of carefully-planned steps.
|
||||
After the crates are rearranged, the desired crates will be at the top
|
||||
of each stack.
|
||||
|
||||
The Elves don't want to interrupt the crane operator during this
|
||||
delicate procedure, but they forgot to ask her which crate will end up
|
||||
where, and they want to be ready to unload them as soon as possible so
|
||||
they can embark.
|
||||
|
||||
They do, however, have a drawing of the starting stacks of crates and
|
||||
the rearrangement procedure (your puzzle input). For example:
|
||||
|
||||
[D]
|
||||
[N] [C]
|
||||
[Z] [M] [P]
|
||||
1 2 3
|
||||
|
||||
move 1 from 2 to 1
|
||||
move 3 from 1 to 3
|
||||
move 2 from 2 to 1
|
||||
move 1 from 1 to 2
|
||||
|
||||
In this example, there are three stacks of crates. Stack 1 contains two
|
||||
crates: crate Z is on the bottom, and crate N is on top. Stack 2
|
||||
contains three crates; from bottom to top, they are crates M, C, and D.
|
||||
Finally, stack 3 contains a single crate, P.
|
||||
|
||||
Then, the rearrangement procedure is given. In each step of the
|
||||
procedure, a quantity of crates is moved from one stack to a different
|
||||
stack. In the first step of the above rearrangement procedure, one crate
|
||||
is moved from stack 2 to stack 1, resulting in this configuration:
|
||||
|
||||
[D]
|
||||
[N] [C]
|
||||
[Z] [M] [P]
|
||||
1 2 3
|
||||
|
||||
In the second step, three crates are moved from stack 1 to stack 3.
|
||||
Crates are moved one at a time, so the first crate to be moved (D) ends
|
||||
up below the second and third crates:
|
||||
|
||||
[Z]
|
||||
[N]
|
||||
[C] [D]
|
||||
[M] [P]
|
||||
1 2 3
|
||||
|
||||
Then, both crates are moved from stack 2 to stack 1. Again, because
|
||||
crates are moved one at a time, crate C ends up below crate M:
|
||||
|
||||
[Z]
|
||||
[N]
|
||||
[M] [D]
|
||||
[C] [P]
|
||||
1 2 3
|
||||
|
||||
Finally, one crate is moved from stack 1 to stack 2:
|
||||
|
||||
[Z]
|
||||
[N]
|
||||
[D]
|
||||
[C] [M] [P]
|
||||
1 2 3
|
||||
|
||||
The Elves just need to know which crate will end up on top of each
|
||||
stack; in this example, the top crates are C in stack 1, M in stack 2,
|
||||
and Z in stack 3, so you should combine these together and give the
|
||||
Elves the message CMZ.
|
||||
|
||||
After the rearrangement procedure completes, what crate ends up on top
|
||||
of each stack?

--- Part Two ---
|
||||
|
||||
As you watch the crane operator expertly rearrange the crates, you
|
||||
notice the process isn't following your prediction.
|
||||
|
||||
Some mud was covering the writing on the side of the crane, and you
|
||||
quickly wipe it away. The crane isn't a CrateMover 9000 - it's a
|
||||
CrateMover 9001.
|
||||
|
||||
The CrateMover 9001 is notable for many new and exciting features: air
|
||||
conditioning, leather seats, an extra cup holder, and the ability to
|
||||
pick up and move multiple crates at once.
|
||||
|
||||
Again considering the example above, the crates begin in the same
|
||||
configuration:
|
||||
|
||||
[D]
|
||||
[N] [C]
|
||||
[Z] [M] [P]
|
||||
1 2 3
|
||||
|
||||
Moving a single crate from stack 2 to stack 1 behaves the same as
|
||||
before:
|
||||
|
||||
[D]
|
||||
[N] [C]
|
||||
[Z] [M] [P]
|
||||
1 2 3
|
||||
|
||||
However, the action of moving three crates from stack 1 to stack 3
|
||||
means that those three moved crates stay in the same order, resulting
|
||||
in this new configuration:
|
||||
|
||||
[D]
|
||||
[N]
|
||||
[C] [Z]
|
||||
[M] [P]
|
||||
1 2 3
|
||||
|
||||
Next, as both crates are moved from stack 2 to stack 1, they retain
|
||||
their order as well:
|
||||
|
||||
[D]
|
||||
[N]
|
||||
[C] [Z]
|
||||
[M] [P]
|
||||
1 2 3
|
||||
|
||||
Finally, a single crate is still moved from stack 1 to stack 2, but now
|
||||
it's crate C that gets moved:
|
||||
|
||||
[D]
|
||||
[N]
|
||||
[Z]
|
||||
[M] [C] [P]
|
||||
1 2 3
|
||||
|
||||
In this example, the CrateMover 9001 has put the crates in a totally
|
||||
different order: MCD.
|
||||
|
||||
Before the rearrangement process finishes, update your simulation so
|
||||
that the Elves know where they should stand to be ready to unload the
|
||||
final supplies. After the rearrangement procedure completes, what crate
|
||||
ends up on top of each stack?
