// --- 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

// 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?
// possible criteria: 12 red cubes, 13 green cubes, and 14 blue cubes
