Advent of Code Solutions

I have set myself a personal challenge to try and get up to date with advent of code, a set of programming challenges released each December.

Each day has 2 related problems, for a total of 50 problems per year. Each button below will show my code solving that problem. Green buttons where I have solved both problems of the day, orange where I have only solved the first one and red where I haven't solved either.

    for c in puzzle_input:

            case '(':
                current_floor += 1
            case ')':
                current_floor -= 1
            case _:
                raise ValueError('Unexpected char')

    return current_floor

def part_2():

    current_floor = 0
    for i, c in enumerate(puzzle_input):
        match c:
            case '(':
                current_floor += 1
            case ')':
                current_floor -= 1
            case _:
                raise ValueError('Unexpected char')

        if current_floor < 0:
            return i + 1
