Weighted Graph:
A graph is termed as weighted graph if each edge of the graph is assigned a weight. The weighted edges stored in the weighted graphs can be stored in adjacency lists.
Weighted edges can be represented using a two-dimensional array. An weighted edge can be represented as “WeightedEdge(u,v,w)”, where “u” and “v” are edges and “w” represents the weight between them.
Example of storing edge in a weighted graph:
Object[][] edges =
{ new Integer(0), new Integer(1), new SomeTypeForWeight(8) };
Spanning Tree:
In computer science, a Spanning Tree for a graph “G” is a subgraph of “G” that it is a free tree connecting all vertices in “V”.

- Take a look at the ADT for the cave system. This ADT may be implemented using a graph. Implement the algorithm using the class you created.arrow_forwardGiven the graph class using the adjacency matrix representation,Implement the DFS algorithm (as discussed in the lecture slide) ongraph using the adjacency matrix representation. You have to use thegraph code as a starting point, and add the DFS method in the graphclass similar to the BFS method already present in the Graph class.arrow_forwardImplement an undirect graph in racket. Please have functions that will do the insertion and deletion. if you have a graph have a find_connection function and explain it while you're showing them how they work.arrow_forward
- Add a new method in UnweightedGraph with the followingheader to return two bipartite sets if the graph is bipartite:public List<List<Integer>> getBipartite();The method returns a List that contains two sublists, each of which contains aset of vertices. If the graph is not bipartite, the method returns null.arrow_forwardAlso implement your algorithm in C++. In each case you should have a graph class (graph.h and graph.cpp). You may use either graph implementation. Please provide main method as well.arrow_forwardI am learning about Depth First Search Graphs in class. In the book we use for class, this pseudocode came up that explains a basic depth-first-search algorithm. I am trying to implement the pseudocode into actual code and I honestly just don't know where to start. I am trying to write an adjacency list, so would that mean that I would have a LinkedList to store an array in? Or is an ArrayList a better choice?arrow_forward
- The number of nodes in the strongest linkedlist is unknown.Is there one that stands out as really long?arrow_forwardIn this assignment, you will design the AddNode and AddEdge methods for the supplied graph data structure. The AddNode and AddEdge methods are to support the construction of undirected (bi-directional) graphs. That is if node A is connected to node B then node B is also connected to node A. In addition to the AddNode and AddEdge methods, create a method called BreadthFirstSearch that accepts a starting node and performs a Breadth First Search of the graph. The algorithm for the breadth first traversal is provided below 1. Add a node to the queue (starting node) 2. While the queue is not empty, dequeue a node 3. Add all unvisited nodes of the dequeued node from step 2 and add them to queue 4. End While Demonstrate your methods by creating the graph depicted in Figure 1 below and running the Breadth First Search on the graph using 0 as the starting node. (see image below) You may use C++, C#, to implement this program as long as the following requirements are met. A C++, or C#…arrow_forwardThe best linkedlist has an unknown number of nodes.Is there one that really sticks out as being quite lengthy?arrow_forward
- Linked lists are used in a specific method to represent adjacency lists on a graph. Do not just make a claim; back it up with an example. Does learning to code not need any prior experience?arrow_forwardHow would I convert this adjacency matrix into an adjacency list and then print the adjacency list using Java, I have implemented my own graph data structure and have tried to do this conversion in displayAsList() unsuccessfully. public class Q5Graph {int maxsize;int wmatrix[][];String labels[];int vertexCount; public Q5Graph() { maxsize = 20; wmatrix = new int[maxsize][maxsize]; labels = new String[maxsize];for(int i=0; i < maxsize; i++) for (int j=0; j< maxsize; j++){ wmatrix[i][j] = 0;}vertexCount = 0;} public void addVertex(String label){if (vertexCount == maxsize) { throw new IllegalArgumentException("Graph is already full!"); } else if (hasVertex(label)) { throw new IllegalArgumentException("Vertex '"+label+"' already exists"); } else {labels[vertexCount] = label;vertexCount++;}} public void addEdge(String label1, String label2, int weight){int v1, v2; if(!hasVertex(label1)){throw new IllegalArgumentException("First Vertex '" +…arrow_forward7- A student has created a plot of y(t)=t^2. He needs to show another graph of z(t)=t^3 in the same plot. But every time he hits the plot() function- MATLAB generates a plot of z(t) vs t but on a different window. What is the error? O It is not possible to plot multiple plots O He is not using the line function Maybe he is using polar() instead of plot() O He is not using the hold functionarrow_forward
