Hi, would like some help as how to approach the following problem:

I have a set of d-dimensional points (e.g (3,5,8,9,5) is a 5-dimensional point), and I need to sort the points on each of the coordinates.
The algorithm that I am trying to implement says that the resulting data structure is a multi-pointer list ((d-1)tuply threaded list), each node of which is threaded in each of the single pointer lists corresponding to the chosen coordinates.

This is a preprocessing stage of my implementation. I need this sorting of the points so that I could use it in a recursive divide and conquer approach to find the maximal elements among the points.

I want to use the STL to solve the problem.

Any ideas as how this preprocessing structure might look like?

AJ.
