Question: Given a graph G = ( V , E ) with costs on the edges, let e be an edge that is required to be

Given a graph G =(V, E) with costs on the edges, let e be an edge that is required
to be included in any minimum spanning tree. So you have to find the minimum cost
set of edges S such that S +{e} is a spanning tree. How will you modify the MST
algorithms to determine such a tree.
Find an algorithm and determine its complexity when k edges are required to be
included.
