The question is to find the balanced spanning tree in O(m*m) , which is the
quesiton in chapeter 13--34 in Ahuja's book: network flow.
Balanced spanning tree is the spanning tree whose difference between the
maximum arc cost and the minimum arc cost is the least one.
Now, I can only find algorithm in O(n*m*m). My method is set every acr as the
samllest one, then cancle the arcs less than it. Then, apply Prim's algorithm.
Finally. choose the samllest one from solutions we will get.
