(5). Run the strongly connected components algorithm on the following directed graphs G. When doing DFS on GR: whenever there is a choice of vertices to explore, always pick the one that is alphabetically first. (15 points) A B C D E F G H I J (A) In what order are the strongly connected components (SCCs) found? (B) Which are source SCCs and which are sink SCCs? (C) Draw the "metagraph" (each meta-node is an SCC of G). (D) What is the minimum number of edges you must add to this graph to make it strongly connected?

Step 1
Both algorithms will find the SCCs in a specific order, which is based on the depth-first search (DFS) traversal of the graph. The SCCs are found in a reverse topological order, meaning that the SCC with no outgoing edges is found first, followed by the SCCs that Show more…

Consider the following directed graph G. List the vertices in descending post order: V1 = { Perform a dfs on GR = (V1, ER), where GR is the reverse graph of G. Parent Stack Visited Complete the following array: Parent Index List the strongly connected components: Draw the graph where the nodes are the strongly connected components of G and there is an edge between two nodes if there is a vertex in first component connected to a vertex in the second component.
