Last year at the same contest my brother came up with the problem AmaX
and I had to "encrease it's ugliness"
You are given a box .We shall consider that one of the corners lays in the point with the coordinates
(0,0,0);You are also given the coordinates of the oposite corner of the box.
Next we consider D holes in the box represented by D spheres.
You have to find the cube with the biggest volume that is complete(it doesn't
intersect with any hole,it doesn't contain one and the coordinates of the cubes corners are integers);
The first line of the input file contains three integers X Y Z the coordinates of the
The second line contais an integer D the number of spheres
The next D lines contain four integers xi,yi,zi,ri the coordinate of the center of the i-th sphere an it's radius
The only line of the output file should contain V the volume of the biggest cube
