'Something' is just array manipulations.
Asuume that (j,k) are a matrix(30 by 30).
For each (j,k) I want to compute sum of distance from (j,k) to all others.
Finally we have to get a minimum among sums.

The obvious question was "What is <Something :-)>?"
It may well be that there is a faster way to express what you want.
Just because a particular program structure is a good structure for
C, that doesn't necessarily mean it's a good structure for any other
programming language.

The magic numbers make me quite sure that there is something interesting
that you are not telling us.
