3. (8 points-7+1) Figure 4 shows an undirected graph G. Assume that the adjacency list lists the edges in alphabetical order. Figure 3: Graph for P3 (a) Apply depth first search (DFS) to graph G, and show the discovery and finish times of each vertex. In the main-loop of DFS, check the vertices in alphabetical the form dsc/fin, where dsc is the discovery time and fin is the finish time. (b) Draw the DFS tree obtained.

Problem 3 (15 points). Let G (V,E) be the following directed graph. a. 1. Draw the reverse graph G of G. 2. Run DFS on G to obtain a post number for each vertex. Assume that in the adjacency list representation of G, vertices are stored alphabetically, and in the list for each vertex, its adjacent vertices are also sorted alphabetically. In other words, the DFS algorithm needs to examine all vertices alphabetically, and when it traverses the adjacent vertices...

Problem 1. (15 points) Consider an undirected connected graph G = (V, E) with edge costs ce > 0 for e € E which are all distinct. (a) [8 points). Let E' CE be defined as the following set of edges: for each node v, E' contains the cheapest of all edges incident on v, i.e., the cheapest edge that has v as one of its endpoints. Is the graph (V, E') connected? Is it acyclic?...
