Day 2: Cube Conundrum
Megathread guidelines
- Keep top level comments as only solutions, if you want to say something other than a solution put it in a new post. (replies to comments can be whatever)
- Code block support is not fully rolled out yet but likely will be in the middle of the event. Try to share solutions as both code blocks and using something such as https://topaz.github.io/paste/ or pastebin (code blocks to future proof it for when 0.19 comes out and since code blocks currently function in some apps and some instances as well if they are running a 0.19 beta)

Was pretty simple in Python with a regex to get the game number, and then the count of color. for part 2 instead of returning true/false whether the game is valid, you just max the count per color. No traps like in the first one, that I’ve seen, so it was surprisingly easy
def process_game(line: str): game_id = int(re.findall(r'game (\d+)*', line)[0]) colon_idx = line.index(":") draws = line[colon_idx+1:].split(";") # print(draws) if is_game_valid(draws): # print("Game %d is possible"%game_id) return game_id return 0 def is_game_valid(draws: list): for draw in draws: red = get_nr_of_in_draw(draw, 'red') if red > MAX_RED: return False green = get_nr_of_in_draw(draw, 'green') if green > MAX_GREEN: return False blue = get_nr_of_in_draw(draw, 'blue') if blue > MAX_BLUE: return False return True def get_nr_of_in_draw(draw: str, color: str): if color in draw: nr = re.findall(r'(\d+) '+color, draw) return int(nr[0]) return 0 # f = open("input.txt", "r") f = open("input_real.txt", "r") lines = f.readlines() sum = 0 for line in lines: sum += process_game(line.strip().lower()) print("Answer: %d"%sum)
