+## Description
+<section id='description'>
+Given two points (x1,y1,z1) and (x2,y2,z2) in three dimensional space, the Manhattan distance  between those points is defined as  |x1-x2|+|y1-y2|+|z1-z2|.
+
+
+Let C(r) be a sphere with radius r and center in the origin O(0,0,0).
+Let I(r) be the set of all points with integer coordinates on the surface of C(r).
+Let S(r) be the sum of the Manhattan distances of all elements of I(r) to the origin O.
+
+
+E.g. S(45)=34518.
+
+
+Find S(1010).
