Point Domination

Given n points in 3-dimensional space having integral co-ordinates, determine for each point, the number of points dominated by the particular point. A point P1(x1, y1, z1) is said to be dominated by a point P2(x2, y2, z2) iff: x1 Input The first line contains a single integer, the value of n. n lines follow, ith of these lines contain the x, y and z co-ordinates, in that order, of the ith p
