Explanation of Solution
Return statement for “getIndex(v)” method if “v” is not in the graph:
The method returns the value “-1” because, the value of “v” is not in the graph.
Explanation:
The method “getIndex()” is to return the index for specified vertex. If the appropriate vertex not in graph then it returns “-1”.
Outcome of “getVertex(index)” method if “index” is not in the graph:
The method returns run time error “IndexOutBoundsException” because the appropriate index value is not available in the graph.
Explanation:
The method “getVertex()” is to return the vertex object for the specified vertex index. If the index not in the graph it throws run time error.
Outcome of “addVertex(v)” method if “v” is already in the graph:
The method returns the Boolean value “false” because the vertex is already added into the graph...

- Consider the graph depicted below. Answer the following questions: What is the degree of vertex a? What is the sum of degrees of all vertices? Who are the neighbors of vertex f? [Please, give the list in alphabetical order, separating letters with only a comma. Do not insert blank spaces] How many zeros does the adjacency matrix of the graph above contain? What is the value on row g and column d of the adjacency matrix?arrow_forwardImplement the flood fill operation on the implicit graph defined by connecting adjacent points that have the same color in an image.arrow_forwardCan you help me with this problem and can you do it step by step. question: Show that every graph with two or more nodes contains two nodes that have equal degrees.arrow_forward
- 1. Construct a simple graph that is a forest with vertices M, N, O, P, Q, R such that the degree of O is 2 and there are 2 components. What is the edge set? 2. Construct a simple graph that is a tree with vertices P,Q,R,S,T,U such that the degree of U is 4. What is the edge set?arrow_forwardI would like to know how to make an undirected graph implementation and how to make a method to find the connectivity between two Nodes assuming the graph is pre-processed ->what is the least amount of time. to check the connection between two nodes?arrow_forward1-Let’s say you have a variable with a static graph associated with it in the backend that will be executed every time you call .compute on that variable. Is there any way to avoid re-computation of the graph every time you call the .compute method? Consider that you have a significant amount of storage available in this case.arrow_forward
- Answer the question attached PLEASE DRAW me the State-Space graph, similar to the example attached pleasearrow_forwardList test paths that achieve node coverage but not edge coverage on the graph. public boolean isPerfect(int x) { int sum = 0; Boolean output; for(int i = 1; i<=(x/2); i ++) { if(x%i == 0) { sum = sum + i; } } if(sum == x) { output = true; }else { output = false; } return output; }arrow_forwardCreate the ErdosRenyiGraph programme, which creates a graph by generating E random pairs of integers between 0 and V1 and using the command line inputs V and E to construct the graph. Self-loops and parallel lines are produced by this generator.arrow_forward
- For a graph where all nodes are connected with other nodes (directly), assume there are "m" total nodes or vertices and "n" total edges. What is the relationship between m and n?* 4 points n = 2m - 1 n = m^2 - 1 n = m n = m(m+1)/2 n = m(m-1)/2 None of the abovearrow_forwardIs it true or false? If it is true, include a (short, but clear) argument why it is true, and if it is false, include a concrete graph which shows that the claim is false.a) If all vertices in a connected graph have even degree, then for whichever two vertices u and v in the graph you choose, there is an Eulerian trail between u and v. b) Given a graph G we construct a new graph H by adding a new vertex v and edges between v and every vertex of G. If G is Hamiltonian, then so is H.c) We know that if a graph has a walk between u and v it also has a path between u and v, for any two vertices u and v. Is it always true that if a graph has a circuit containing u and v it also has a cycle containing u and v? d) The complete bipartite graph K?,?(lowered indicies) is Hamiltonian if and only if m = n ≥ 2.arrow_forwardWhat is a reason for using an adjacency matrix instead of an adjacency list to represent a graph?arrow_forward
