We cannot do it without computing distances of each node from all other
nodes. So to begin with, construct a matrix representation of the graph
with distances filled in for every pair of points.
Proceed to calculate the minimum spanning tree of such a weighted graph.

I have been trying this problem which is from a past hacker cup.I am
getting wrong answer.http://www.spoj.pl/problems/NFACTOR/
My approach:
1.Count the number of prime factors of a number(trivial way)
for(int i=2;i*2=100;i++) number_of_factors[i]=1; //atleast 1 factor
that is 2
for(int
We can calculate the centroid of all d points and then calculate their
individual distances from it .The point with the minimum distance will
be the answer.

How will you implement a graph data structure ?
Give an linked implementation as we do not know how many nodes will be
there and how many edges will be there.
Make a copy of this graph..

I think if we calculate the center of the graph that will give the
solution, to do that
1. find the eccentricity of every node using all pair shortest path algo's
( Floyd warshall).
2. The node which is having min eccentricity is your P.
