编程题åc了91%,有没有人都对的帮我看看哪些corner case没考虑到?
import math
while 1:
a=[]
s = input()
if s != "":
for x in s.split():
a.append(int(x))
r, circle_x, circle_y, x1, y1, x2, y2 = a
rec_x, rec_y = (x1+x2)/2, (y1+y2)/2
distance = math.sqrt((circle_x-rec_x)**2 + (circle_y-rec_y)**2)
if abs(circle_y - rec_y) == 0:
distance_2 = (x2 - x1)/2
elif abs(circle_x-rec_x) == 0:
distance_2 = (y2 - y1)/2
else:
tan1 = abs(circle_y - rec_y) / abs(circle_x-rec_x)
tan2 = (y2 - y1) / (x2 - x1)
if tan1 < tan2:
#abs(circle_x-rec_x) / distance = (x2-x1)/2 / distance_2
distance_2 = distance * (x2-x1)/2 / abs(circle_x-rec_x)
if tan1 >= tan2:
#abs(circle_y-rec_y) / distance = (y2-y1)/2 / distance_2
distance_2 = distance * (y2-y1)/2 / abs(circle_y-rec_y)
if distance_2 + r < distance:
print('False')
else:
print('True')
