Discussion of Problem 1317. Hail

Varun Sharma Can't Understand the Problem [1] // Problem 1317. Hail 27 Apr 2009 05:26
Hi,

How come the answer for the test case is three when all the points 0,0 1,1 2,2 3,3 and 4,4 are within 50 meters of the laser. The answer should be 5 ? isn't it ? Also, what are the roles of fence and convex polygon here ? can't seem to get that as well !

Thanks

Laser can't shoot through polygon and height of wall is important.
