3. Given a directed graph G < V E >, we define its transpose Gr < V.E1 > to be the graph such that ET-{ < v, u >:< u, v >EE). In other words, GT has the same number of edges as in G, but the directions of the edges are reversed. Draw the transpose of the following graph: ta Perform DFS on the original graph G, and write down the start and finish times for each vertex in...
Give the adjacency matrix representation and the adjacency lists representation for the graph G_1. Assume that vertices (e.g., in adjacency lists) are ordered alphabetically. For the following problems, assume that vertices are ordered alphabetically in the adjacency lists (thus you will visit adjacent vertices in alphabetical order). Execute a Breadth-First Search on the graph G_1, starting on vertex a. Specifiy the visit times for each node of the graph. Execute a Depth-First Search on the graph G_1 starting on vertex...
Show the operation of depth-first search (DFS) on the graph of Figure 1 starting from vertex q. Always process vertices in alphabetical order. Show the discovery and finish times for each vertex, and the classification of each edge. (b) A depth-first forest classifies the edges of a graph into tree, back, forward, and cross edges. A breadth-first search (BFS) tree can also be used to classify the edges reachable from the source of the search into the same four categories....
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. 3. (8 points-7+1) Figure...
Problem 2 [10 points] Depth-First Search Write inside each vertex in the following graph the discovery and finishing times in the format discovery/finish. Assume DFS considers the vertices in alphabetical order (A,B,C,....X,Y,Z), and assume that each adjacency list is ordered alphabetically W 1/ х у
Execute DFS on the graph below, starting in node a. Whenever you have a choice which vertex to visit next, choose the next vertex in the adjacency list of the vertex (e.g., when you have reached node e, you must first try to visit node f, then g, and then . Indicate the outcome of the algorithm by labeling the edges of the graph either as T (tree edge) F (forward edge), B (back edge), or C (cross edge). Label...
Consider the following directed graph for each of the problems: 1. Perform a breadth-first search on the graph assuming that the vertices and adjacency lists are listed in alphabetical order. Show the breadth-first search tree that is generated. 2. Perform a depth-first search on the graph assuming that the vertices and adjacency lists are listed in alphabetical order. Classify each edge as tree, back or cross edge. Label each vertex with its start and finish time. 3. Remove all the...
Show how depth-first search works on the graph of Figure 22.6. Assume that the for loop of lines 5–7 of the DFS procedure considers the vertices in reverse alphabetical order, and assume that each adjacency list is ordered alphabetically.

Please help me with 2 (c), thank you!!! Figure 2: 4 10 Figure 3:1 4 Problems 1. Trace BFS on the following graphs. For each vertex, record its color, parent, and distance fields, draw the resulting BFS tree, and determine the order in which vertices are added to the Queue.

ignore red marks. Thanks 10. (16) You will compute the strongly connected components of this graph in three steps. a. STRONGLY-CONNECTED-COMPONENTS (G) (7) Perform a depth-first search on call DFS(G) to compute finishing times w/ for each vertex the following graph. (To make 2 compute GT this easier to grade, everyone call DFS(GT), but in the main loop of DFS, consider the vertices in order of decreasing wf (as computed in line 1) please start with vertex "a" and 4...
