498_A. Crazy Town
Crazy Town is a plane on which there are n infinite line roads. Each road is defined by the equation aix + biy + ci = 0, where ai and bi are not both equal to the zero. The roads divide the plane into connected regions, possibly of infinite space. Let's call each such region a block. We define an intersection as the po...

The roads divide the plane into connected regions, possibly of infinite space. Let's call each such region a block. We define an intersection as the po...
