• Wild dog assertion

Question related to mission Wild Dogs


Seems to me this assertion is wrong:

assert wild_dogs([(10, 10), (21, 18)]) == 0

Distance 0 means the point (0,0) and the point (10, 10) are connected by the one line, if that's the case, then the point (21, 18) cannot be in that same line. Or am I missing something?

Thanks in advance.

Best! JJD
