Day 6: Wait for It

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/ , pastebin, or github (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)

    Language: Python

    Part 1

    Not much to say… this was pretty straightforward.

    def race(charge_time: int, total_time: int) -> int:
    return charge_time * (total_time - charge_time)

def main(stream=sys.stdin) -> None:
    times     = [int(t) for t in stream.readline().split(':')[-1].split()]
    distances = [int(d) for d in stream.readline().split(':')[-1].split()]
    product   = 1

    for time, distance in zip(times, distances):
        ways     = [c for c in range(1, time + 1) if race(c, time) > distance]
        product *= len(ways)

    print(product)
    Part 2

    Probably could have done some math, but didn’t need to :]

    def race(charge_time: int, total_time: int):
    return charge_time * (total_time - charge_time)

def main(stream=sys.stdin) -> None:
    time     = int(''.join(stream.readline().split(':')[-1].split()))
    distance = int(''.join(stream.readline().split(':')[-1].split()))
    ways     = [c for c in range(1, time + 1) if race(c, time) > distance]
    print(len(ways))
