br0xen (AoC++) 26*
|
||||
|
||||
--- Day 12: Hill Climbing Algorithm ---
|
||||
|
||||
You try contacting the Elves using your handheld device, but the river you're following must be
|
||||
too low to get a decent signal.
|
||||
|
||||
You ask the device for a heightmap of the surrounding area (your puzzle input). The heightmap
|
||||
shows the local area from above broken into a grid; the elevation of each square of the grid is
|
||||
given by a single lowercase letter, where a is the lowest elevation, b is the next-lowest, and
|
||||
so on up to the highest elevation, z.
|
||||
|
||||
Also included on the heightmap are marks for your current position (S) and the location that
|
||||
should get the best signal (E). Your current position (S) has elevation a, and the location that
|
||||
should get the best signal (E) has elevation z.
|
||||
|
||||
You'd like to reach E, but to save energy, you should do it in as few steps as possible. During
|
||||
each step, you can move exactly one square up, down, left, or right. To avoid needing to get out
|
||||
your climbing gear, the elevation of the destination square can be at most one higher than the
|
||||
elevation of your current square; that is, if your current elevation is m, you could step to
|
||||
elevation n, but not to elevation o. (This also means that the elevation of the destination
|
||||
square can be much lower than the elevation of your current square.)
|
||||
|
||||
For example:
|
||||
|
||||
Sabqponm
|
||||
abcryxxl
|
||||
accszExk
|
||||
acctuvwj
|
||||
abdefghi
|
||||
|
||||
Here, you start in the top-left corner; your goal is near the middle. You could start by moving
|
||||
down or right, but eventually you'll need to head toward the e at the bottom. From there, you
|
||||
can spiral around to the goal:
|
||||
|
||||
v..v<<<<
|
||||
>v.vv<<^
|
||||
.>vv>E^^
|
||||
..v>>>^^
|
||||
..>>>>>^
|
||||
|
||||
In the above diagram, the symbols indicate whether the path exits each square moving up (^),
|
||||
down (v), left (<), or right (>). The location that should get the best signal is still E, and .
|
||||
marks unvisited squares.
|
||||
|
||||
This path reaches the goal in 31 steps, the fewest possible.
|
||||
|
||||
What is the fewest steps required to move from your current position to the location that should
|
||||
get the best signal?
|
||||
|
||||
Your puzzle answer was 449.
|
||||
|
||||
--- Part Two ---
|
||||
|
||||
As you walk up the hill, you suspect that the Elves will want to turn this into a hiking trail.
|
||||
The beginning isn't very scenic, though; perhaps you can find a better starting point.
|
||||
|
||||
To maximize exercise while hiking, the trail should start as low as possible: elevation a. The
|
||||
goal is still the square marked E. However, the trail should still be direct, taking the fewest
|
||||
steps to reach its goal. So, you'll need to find the shortest path from any square at elevation
|
||||
a to the square marked E.
|
||||
|
||||
Again consider the example from above:
|
||||
|
||||
Sabqponm
|
||||
abcryxxl
|
||||
accszExk
|
||||
acctuvwj
|
||||
abdefghi
|
||||
|
||||
Now, there are six choices for starting position (five marked a, plus the square marked S that
|
||||
counts as being at elevation a). If you start at the bottom-left square, you can reach the goal
|
||||
most quickly:
|
||||
|
||||
...v<<<<
|
||||
...vv<<^
|
||||
...v>E^^
|
||||
.>v>>>^^
|
||||
>^>>>>>^
|
||||
|
||||
This path reaches the goal in only 29 steps, the fewest possible.
|
||||
|
||||
What is the fewest steps required to move starting from any square with elevation a to the
|
||||
location that should get the best signal?
|
||||
|
||||
Your puzzle answer was 443.
|
||||
|
||||
Both parts of this puzzle are complete! They provide two gold stars: **

|

--- Day 13: Distress Signal ---
|
||||
|
||||
You climb the hill and again try contacting the Elves. However, you instead receive a signal you
|
||||
weren't expecting: a distress signal.
|
||||
|
||||
Your handheld device must still not be working properly; the packets from the distress signal
|
||||
got decoded out of order. You'll need to re-order the list of received packets (your puzzle
|
||||
input) to decode the message.
|
||||
|
||||
Your list consists of pairs of packets; pairs are separated by a blank line. You need to
|
||||
identify how many pairs of packets are in the right order.
|
||||
|
||||
For example:
|
||||
|
||||
[1,1,3,1,1]
|
||||
[1,1,5,1,1]
|
||||
|
||||
[[1],[2,3,4]]
|
||||
[[1],4]
|
||||
|
||||
[9]
|
||||
[[8,7,6]]
|
||||
|
||||
[[4,4],4,4]
|
||||
[[4,4],4,4,4]
|
||||
|
||||
[7,7,7,7]
|
||||
[7,7,7]
|
||||
|
||||
[]
|
||||
[3]
|
||||
|
||||
[[[]]]
|
||||
[[]]
|
||||
|
||||
[1,[2,[3,[4,[5,6,7]]]],8,9]
|
||||
[1,[2,[3,[4,[5,6,0]]]],8,9]
|
||||
|
||||
Packet data consists of lists and integers. Each list starts with [, ends with ], and contains
|
||||
zero or more comma-separated values (either integers or other lists). Each packet is always a
|
||||
list and appears on its own line.
|
||||
|
||||
When comparing two values, the first value is called left and the second value is called right.
|
||||
Then:
|
||||
|
||||
• If both values are integers, the lower integer should come first. If the left integer is
|
||||
lower than the right integer, the inputs are in the right order. If the left integer is
|
||||
higher than the right integer, the inputs are not in the right order. Otherwise, the inputs
|
||||
are the same integer; continue checking the next part of the input.
|
||||
• If both values are lists, compare the first value of each list, then the second value, and
|
||||
so on. If the left list runs out of items first, the inputs are in the right order. If the
|
||||
right list runs out of items first, the inputs are not in the right order. If the lists are
|
||||
the same length and no comparison makes a decision about the order, continue checking the
|
||||
next part of the input.
|
||||
• If exactly one value is an integer, convert the integer to a list which contains that
|
||||
integer as its only value, then retry the comparison. For example, if comparing [0,0,0] and
|
||||
2, convert the right value to [2] (a list containing 2); the result is then found by instead
|
||||
comparing [0,0,0] and [2].
|
||||
|
||||
Using these rules, you can determine which of the pairs in the example are in the right order:
|
||||
|
||||
== Pair 1 ==
|
||||
- Compare [1,1,3,1,1] vs [1,1,5,1,1]
|
||||
- Compare 1 vs 1
|
||||
- Compare 1 vs 1
|
||||
- Compare 3 vs 5
|
||||
- Left side is smaller, so inputs are in the right order
|
||||
|
||||
== Pair 2 ==
|
||||
- Compare [[1],[2,3,4]] vs [[1],4]
|
||||
- Compare [1] vs [1]
|
||||
- Compare 1 vs 1
|
||||
- Compare [2,3,4] vs 4
|
||||
- Mixed types; convert right to [4] and retry comparison
|
||||
- Compare [2,3,4] vs [4]
|
||||
- Compare 2 vs 4
|
||||
- Left side is smaller, so inputs are in the right order
|
||||
|
||||
== Pair 3 ==
|
||||
- Compare [9] vs [[8,7,6]]
|
||||
- Compare 9 vs [8,7,6]
|
||||
- Mixed types; convert left to [9] and retry comparison
|
||||
- Compare [9] vs [8,7,6]
|
||||
- Compare 9 vs 8
|
||||
- Right side is smaller, so inputs are not in the right order
|
||||
|
||||
== Pair 4 ==
|
||||
- Compare [[4,4],4,4] vs [[4,4],4,4,4]
|
||||
- Compare [4,4] vs [4,4]
|
||||
- Compare 4 vs 4
|
||||
- Compare 4 vs 4
|
||||
- Compare 4 vs 4
|
||||
- Compare 4 vs 4
|
||||
- Left side ran out of items, so inputs are in the right order
|
||||
|
||||
== Pair 5 ==
|
||||
- Compare [7,7,7,7] vs [7,7,7]
|
||||
- Compare 7 vs 7
|
||||
- Compare 7 vs 7
|
||||
- Compare 7 vs 7
|
||||
- Right side ran out of items, so inputs are not in the right order
|
||||
|
||||
== Pair 6 ==
|
||||
- Compare [] vs [3]
|
||||
- Left side ran out of items, so inputs are in the right order
|
||||
|
||||
== Pair 7 ==
|
||||
- Compare [[[]]] vs [[]]
|
||||
- Compare [[]] vs []
|
||||
- Right side ran out of items, so inputs are not in the right order
|
||||
|
||||
== Pair 8 ==
|
||||
- Compare [1,[2,[3,[4,[5,6,7]]]],8,9] vs [1,[2,[3,[4,[5,6,0]]]],8,9]
|
||||
- Compare 1 vs 1
|
||||
- Compare [2,[3,[4,[5,6,7]]]] vs [2,[3,[4,[5,6,0]]]]
|
||||
- Compare 2 vs 2
|
||||
- Compare [3,[4,[5,6,7]]] vs [3,[4,[5,6,0]]]
|
||||
- Compare 3 vs 3
|
||||
- Compare [4,[5,6,7]] vs [4,[5,6,0]]
|
||||
- Compare 4 vs 4
|
||||
- Compare [5,6,7] vs [5,6,0]
|
||||
- Compare 5 vs 5
|
||||
- Compare 6 vs 6
|
||||
- Compare 7 vs 0
|
||||
- Right side is smaller, so inputs are not in the right order
|
||||
|
||||
What are the indices of the pairs that are already in the right order? (The first pair has index
|
||||
1, the second pair has index 2, and so on.) In the above example, the pairs in the right order
|
||||
are 1, 2, 4, and 6; the sum of these indices is 13.
|
||||
|
||||
Determine which pairs of packets are already in the right order. What is the sum of the indices
|
||||
of those pairs?
|
||||
|
||||
Your puzzle answer was 5905.
|
||||
|
||||
--- Part Two ---
|
||||
|
||||
Now, you just need to put all of the packets in the right order. Disregard the blank lines in
|
||||
your list of received packets.
|
||||
|
||||
The distress signal protocol also requires that you include two additional divider packets:
|
||||
|
||||
[[2]]
|
||||
[[6]]
|
||||
|
||||
Using the same rules as before, organize all packets - the ones in your list of received packets
|
||||
as well as the two divider packets - into the correct order.
|
||||
|
||||
For the example above, the result of putting the packets in the correct order is:
|
||||
|
||||
[]
|
||||
[[]]
|
||||
[[[]]]
|
||||
[1,1,3,1,1]
|
||||
[1,1,5,1,1]
|
||||
[[1],[2,3,4]]
|
||||
[1,[2,[3,[4,[5,6,0]]]],8,9]
|
||||
[1,[2,[3,[4,[5,6,7]]]],8,9]
|
||||
[[1],4]
|
||||
[[2]]
|
||||
[3]
|
||||
[[4,4],4,4]
|
||||
[[4,4],4,4,4]
|
||||
[[6]]
|
||||
[7,7,7]
|
||||
[7,7,7,7]
|
||||
[[8,7,6]]
|
||||
[9]
|
||||
|
||||
Afterward, locate the divider packets. To find the decoder key for this distress signal, you
|
||||
need to determine the indices of the two divider packets and multiply them together. (The first
|
||||
packet is at index 1, the second packet is at index 2, and so on.) In this example, the divider
|
||||
packets are 10th and 14th, and so the decoder key is 140.
|
||||
|
||||
Organize all of the packets into the correct order. What is the decoder key for the distress
|
||||
signal?
|
||||
|
||||
Your puzzle answer was 21691.
|
||||
|
||||
Both parts of this puzzle are complete! They provide two gold stars: **
