--- Day 2: Cube Conundrum ---
|
||||||
|
|
||||||
|
You're launched high into the atmosphere! The apex of your trajectory just
|
||||||
|
barely reaches the surface of a large island floating in the sky. You gently
|
||||||
|
land in a fluffy pile of leaves. It's quite cold, but you don't see much snow.
|
||||||
|
An Elf runs over to greet you.
|
||||||
|
|
||||||
|
The Elf explains that you've arrived at Snow Island and apologizes for the lack
|
||||||
|
of snow. He'll be happy to explain the situation, but it's a bit of a walk, so
|
||||||
|
you have some time. They don't get many visitors up here; would you like to play
|
||||||
|
a game in the meantime?
|
||||||
|
|
||||||
|
As you walk, the Elf shows you a small bag and some cubes which are either red,
|
||||||
|
green, or blue. Each time you play this game, he will hide a secret number of
|
||||||
|
cubes of each color in the bag, and your goal is to figure out information about
|
||||||
|
the number of cubes.
|
||||||
|
|
||||||
|
To get information, once a bag has been loaded with cubes, the Elf will reach
|
||||||
|
into the bag, grab a handful of random cubes, show them to you, and then put
|
||||||
|
them back in the bag. He'll do this a few times per game.
|
||||||
|
|
||||||
|
You play several games and record the information from each game (your puzzle
|
||||||
|
input). Each game is listed with its ID number (like the 11 in Game 11: ...)
|
||||||
|
followed by a semicolon-separated list of subsets of cubes that were revealed
|
||||||
|
from the bag (like 3 red, 5 green, 4 blue).
|
||||||
|
|
||||||
|
For example, the record of a few games might look like this:
|
||||||
|
|
||||||
|
Game 1: 3 blue, 4 red; 1 red, 2 green, 6 blue; 2 green
|
||||||
|
Game 2: 1 blue, 2 green; 3 green, 4 blue, 1 red; 1 green, 1 blue
|
||||||
|
Game 3: 8 green, 6 blue, 20 red; 5 blue, 4 red, 13 green; 5 green, 1 red
|
||||||
|
Game 4: 1 green, 3 red, 6 blue; 3 green, 6 red; 3 green, 15 blue, 14 red
|
||||||
|
Game 5: 6 red, 1 blue, 3 green; 2 blue, 1 red, 2 green
|
||||||
|
|
||||||
|
In game 1, three sets of cubes are revealed from the bag (and then put back
|
||||||
|
again). The first set is 3 blue cubes and 4 red cubes; the second set is 1 red
|
||||||
|
cube, 2 green cubes, and 6 blue cubes; the third set is only 2 green cubes.
|
||||||
|
|
||||||
|
The Elf would first like to know which games would have been possible if the bag
|
||||||
|
contained only 12 red cubes, 13 green cubes, and 14 blue cubes?
|
||||||
|
|
||||||
|
In the example above, games 1, 2, and 5 would have been possible if the bag had
|
||||||
|
been loaded with that configuration. However, game 3 would have been impossible
|
||||||
|
because at one point the Elf showed you 20 red cubes at once; similarly, game 4
|
||||||
|
would also have been impossible because the Elf showed you 15 blue cubes at
|
||||||
|
once. If you add up the IDs of the games that would have been possible, you get
|
||||||
|
8.
|
||||||
|
|
||||||
|
Determine which games would have been possible if the bag had been loaded with
|
||||||
|
only 12 red cubes, 13 green cubes, and 14 blue cubes. What is the sum of the IDs
|
||||||
|
of those games?

--- Part Two ---
|
||||||
|
|
||||||
|
The Elf says they've stopped producing snow because they aren't getting any
|
||||||
|
water! He isn't sure why the water stopped; however, he can show you how to get
|
||||||
|
to the water source to check it out for yourself. It's just up ahead!
|
||||||
|
|
||||||
|
As you continue your walk, the Elf poses a second question: in each game you
|
||||||
|
played, what is the fewest number of cubes of each color that could have been in
|
||||||
|
the bag to make the game possible?
|
||||||
|
|
||||||
|
Again consider the example games from earlier:
|
||||||
|
|
||||||
|
Game 1: 3 blue, 4 red; 1 red, 2 green, 6 blue; 2 green
|
||||||
|
Game 2: 1 blue, 2 green; 3 green, 4 blue, 1 red; 1 green, 1 blue
|
||||||
|
Game 3: 8 green, 6 blue, 20 red; 5 blue, 4 red, 13 green; 5 green, 1 red
|
||||||
|
Game 4: 1 green, 3 red, 6 blue; 3 green, 6 red; 3 green, 15 blue, 14 red
|
||||||
|
Game 5: 6 red, 1 blue, 3 green; 2 blue, 1 red, 2 green
|
||||||
|
|
||||||
|
In game 1, the game could have been played with as few as 4 red, 2 green, and 6
|
||||||
|
blue cubes. If any color had even one fewer cube, the game would have been
|
||||||
|
impossible.
|
||||||
|
|
||||||
|
Game 2 could have been played with a minimum of 1 red, 3 green, and 4 blue cubes.
|
||||||
|
Game 3 must have been played with at least 20 red, 13 green, and 6 blue cubes.
|
||||||
|
Game 4 required at least 14 red, 3 green, and 15 blue cubes.
|
||||||
|
Game 5 needed no fewer than 6 red, 3 green, and 2 blue cubes in the bag.
|
||||||
|
|
||||||
|
The power of a set of cubes is equal to the numbers of red, green, and blue
|
||||||
|
cubes multiplied together. The power of the minimum set of cubes in game 1 is
|
||||||
|
48. In games 2-5 it was 12, 1560, 630, and 36, respectively. Adding up these
|
||||||
|
five powers produces the sum 2286.
|
||||||
|
|
||||||
|
