Problem D. Ali The Multi-billionaire

Announcement
Some test data in Problem D is broken so to skip those tests do the following: output 66815857 if (n == 1874 && m == 11511) and 3659837 if (n == 100 && m == 6875) then terminate the program without taking further input. (Don't blame me I am not the author I am just trying to help)

Problem H. Are You Safe?
*****
Does the order in which the points are outputted for the polygon matter? That is, does it matter which point is listed first?
Yes, it does matter. The first point should be the one with smallest x coordinate. If there is more then one such point, choose the one with smallest y coordinate. (The statement does not mention it because it is a very bad statement)
