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....

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...

Q2. Show the execution trace of DFS on the following directed graph. You must show discovery time v.d, finish time v.f, and the v.color for each node as the algorithm progresses. Indicate all tree edges, back edges, forward edges, and cross edges when the final DFS forest is constructed. Assume that the edges going out from a vertex are processed in alphabetical order and that each adjacency list is ordered alphabetically.

vertices and adjacency lists
are listed in alphabetical order. Show the breadth-first search
tree that is generated.

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.

Run BFS on the graph above
starting from vertex 0 and list the vertices in order of their
first visit.. Assume the adjacency list is in descending sorted
order based on the label of the vertices. For example, when
iterating through the edges pointing from 0, first consider the
edge 0 → 6, then 0 → 3, and finally 0 → 1.
