4. Consider the following undirected weighted praph: 15 18 5 6 16 17 19 10 2 11 27 13 (1) Give the list of edge weights in the minimum spanning tree (MST) in the order that Kruskal's algorithm inserts them. (2) Give the list of edge weights in the MST in the order that Prim's algorithm inserts them, assuming that it starts at the black vertex
