Write a C# method to determine if a vertex has no successors and a method for removing a vertex from a graph.
Step by step
Solved in 3 steps
- Create the following graph. Implement the following functions. 1. addEdge() that takes two vertices as two parameters and creates an Edge between them. 2. nonAdjacentVertices() that takes a single vertex as parameter, and returns an array of vertices that are NOT adjacent to that vertex. 3. Write a function addUnknownVertices() that takes a vertex as a parameters, and creates an Edge with the vertices that are NOT adjacent to it. 4. Write a method searchVertex() which takes an array of Vertices as parameters. The first member of the array will be the starting vertex and the last member will be the Vertex you want to reach. For example searchVertex(Vertex 0, Vertex 4, Vertex 3) will output “Vertex cannot be reached” since you can reach from 0 to 4, but cannot from 4 to 3. Again, searchVertex(Vertex 0, Vertex 1, Vertex 2, Node 3) will output “Vertex can be reached” since you can reach from 0 to 1, 1 to 2, 2 to 3.Write a program (WAP) in c/c++ to create an undirected graph using adjacency list representation. Number of nodes and edges should be taken from the user. After creating the graph, perform following operations:(i) Search a node. Take the node number from the user. If the node is found then print its associated edges.(ii) Insert a node in the graph. (iii) Insert an edge in the graph. Take the node numbers from the user between which the edge is to be inserted.(iv) Delete a node from the graph. Take the node number to be deleted from the user.(v) Apply DFS on the graph and print the graph traversal.(vi) Apply BFS on the graph and print the graph traversalWrite a function, called getadjacents, that receives a T item and an empty queue. The function will fill the queue with all items stored in vertices that are adjacent to the vertex containing the item sent as a parameter. The function belongs to a graph class with an adjacency list implementation. C++
- Using the graph in the question: Write Java code to create an Adjacency Matrix M to represent the graph. Write Java code to create an Adjacency List L to represent the graph.Application "networkx" library is used for implementing graphs. Draw a graph using this library in python. (Hint: use 'add_node()", 'add_edge()' functions to draw edges and nodes). Construct the graph shown in figure using python language. Also, plot the graph using matplotlib library, Traverse the graph using DFS, and output the DFS order. 2class Dijkstra(): """ A fully connected directed graph with edge weights """ def __init__(self, vertex_count): self.vertex_count = vertex_count self.graph = [[0 for _ in range(vertex_count)] for _ in range(vertex_count)] def min_distance(self, dist, min_dist_set): """ Find the vertex that is closest to the visited set """ min_dist = float("inf") for target in range(self.vertex_count): if min_dist_set[target]: continue if dist[target] < min_dist: min_dist = dist[target] min_index = target return min_index def dijkstra(self, src): """ Given a node, returns the shortest distance to every other node """ dist = [float("inf")] * self.vertex_count dist[src] = 0 min_dist_set = [False] * self.vertex_count for _ in range(self.vertex_count): #minimum distance vertex that is not processed…
- Help in C++ please: Write a program (in main.cpp) that: Prompts the user for a filename containing node data. Outputs the minimal spanning tree for a given graph. You will need to implement the createSpanningGraph method in minimalSpanTreeType.h to create the graph and the weight matrix. There are a few tabs: main.cpp, graphType.h, linkedList.h, linkedQueue.h, queueADT.h, minimalSpanTreeType.h, and then two data files labeled: CH20_Ex21Data.txt, CH20Ex4Data.txtWrite a C/C++ program to implement Floyd Warshall Algorithm that displays the matrix after each step. Elements should be right-aligned in proper columns. Use your program on the graph given below. Give the source code and the runtime screen. 3 8. 1 4 3 2.The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
- Code in Java only In a rooted tree, the lowest common ancestor (or LCA for short) of two vertices u and v is defined as the lowest vertex that is ancestor of both that two vertices. Given a tree of N vertices, you need to answer the question of the form "r u v" which means if the root of the tree is at r then what is LCA of u and v.
