Jour 7

Rien de bien complique ajd, mais j'ai quand meme perdu un peu de temps sur la premiere partie, faute de tenir compte du fait qu'un splitter devait voir passer un beam pour etre active... Ce qui donne

from typing import Iterable, NamedTuple
class Position(NamedTuple):
 x: int
 y: int
class Manifolder:
 def __init__(self, data: list[str]) -> None:
 self.grid = data
 self.height = len(self.grid)
 self.width = len(self.grid[0])
 def is_divider(self, pos: Position) -> bool:
 return self.grid[pos.y][pos.x] == '^'
 def divisions(self) -> Iterable[int]:
 beams = {self.grid[0].index('S')}
 for y in range(2, self.height, 2):
 splitters = [p for p in map(lambda x: Position(x, y), range(self.width)) if self.is_divider(p) and p.x in beams]
 beams |= {p.x-1 for p in splitters}
 beams |= {p.x+1 for p in splitters}
 beams -= {p.x for p in splitters}
 yield len(splitters)
 def timelines(self) -> int:
 timelines = { i: int(self.grid[0][i] == 'S') for i in range(self.width)}
 for y in range(2, self.height, 2):
 splitters = [p for p in map(lambda x: Position(x, y), range(self.width)) if self.is_divider(p) and p.x in timelines.keys()]
 for s in splitters:
 v = timelines[s.x]
 timelines[s.x] = 0
 timelines[s.x-1] += v
 timelines[s.x+1] += v
 return sum(timelines.values())
def exo1(data: list[str]) -> int:
 return sum(Manifolder(data).divisions())
def exo2(data: list[str]) -> int:
 return Manifolder(data).timelines()
