Réponse à "Comment écrire le problème F05 en temps réel hors ligne"

Je n'ai pas pu venir sur place. Environ 2 heures au total. J'ai trouvé une application iPhone Python dans le train. Déboguer en l'utilisant.

Les raisons pour lesquelles cela n'a pas fonctionné sur le site sont les suivantes.

La logique d'arrondi était fausse. Je n'ai pas utilisé round et j'ai ajouté 0,5. Les nombres négatifs entraîneront des résultats inattendus.
L'angle de rotation était incorrect. Il devrait faire -90 degrés, mais c'était 90 degrés.
L'utilisation de i et j dans la ligne de plusieurs tableaux a été inversée.

`main.py`



## yhpg F05

W = H = 5

def rotate(x, y):
    d = - math.pi / 2
    xd = x * math.cos(d) - y * math.sin(d)
    yd = x * math.sin(d) + y * math.cos(d)
    return (int(round(xd)), int(round(yd)))

def make_key(x, y):
   return str(x) + "," +str(y)

def resolve(data):
    center, rows = data.split(":")
    row = rows.split("/")

    ax = [-1, 0, 1, 2, 3]

    bx = [-2, -1, 1, 2, 3]
    by = [2, 1, -1, -2, -3]

    field = {}

    locx, locy = None, None
    if center == 'a':
        locx, locy = ax, ay
    else:
        locx, locy = bx, by

        for j in range(H):
            result[j] += field[make_key(locx[i], locy[j])]

    return '/'.join(result)
