Markup the BFS code so that it can determine if the graph g is connected or not. Further modify the BFS code so that that it is possible to determine the number of connected components and their membership (i.e., which vertices belong to which component). // Connectivity Checker and Identifier public static Integer[] ProcessOrderInBFS(Graph g) { int foundCount = 1; Integer[] processOrder = new Integer[g.size(O]; for (int i = 0; i q = new LinkedList(); int currNode = 0; Integer[] adjVector = null; q. add(startVertex); processorder[startVertex] = foundCount; foundCount++; while(!q.isEmpty()) { currNode = q.remove(); adjVector = g.getAdjVector(currNode); for (int i = 0; i < g.size(); i++) { if(adjVector[i] == 1 && processOrder[i] == 0) { q. add(i); processorder[i] = foundCount; foundCount++; } } } return foundCount;
When a vertex Q is connected by an edge to a vertex K, what is the term for the relationship between Q and K? *a) Q and K are "insecure."b) Q and K are "incident."c) Q and K are "adjacent."d) Q and K are "isolated."
Write to code describes how to create the links dataset that represents the input graph. In this particular case, the links represent a directed network. The links dataset has only the nodes identification, which means, the from and to variables. The link weights in the transitive closure problem are irrelevant. In other words, it doesn’t matter the cost or the weight of the links, the algorithm searches for the possible paths to connect the nodes within the input graph. If there is a link or a set of links, no matter the weights, that connects node i to node j, that is the matter.

ADT Graph Iterator: Create either a DFS graph iterator or a BFS graph iterator by implementing java.util.lterator interface. An ADT graph iterator should have a reference to an ADT graph. It should also have a DFS search method or a BFS search method.
