Problem 1493. Dots in a Diamond

Created by Yaroslav in Community

Return how many Diamond Cubic lattice grid points there are inside a 3D sphere of radius r centred at (0,0,0) (including points on the edge).

Set the distance between two adjacent lattice grid points to be e =1. In addition, assume that (0,0,0) is a grid point.

Neither string operations nor interpolations are allowed!
