Let's say that you compute the minimum spanning tree as the list of edges called MST. Now, MST contains triples (u, v, weight). What you can do is to iterate over edges in MST and for each such edge (u, v, weight) append a tuple (v, weight) to the adjacency list of u, and also append a tuple (u, weight) to the adjacency list of v. drill bit cabinet factory
