Consider the java Graph class below which represents an undirected graph in an adjacency list. How would you add a method to delete an edge from the graph? // Exercise 4.1.3 (Solution published at http://algs4.cs.princeton.edu/) package algs41; import stdlib.*; import algs13.Bag; /** * The <code>Graph</code> class represents an undirected graph of vertices * named 0 through V-1. * It supports the following operations: add an edge to the graph, * iterate over all of the neighbors adjacent to a vertex....
How would I traverse through this graph? Provide example code, please! class Edge { int src, dest; Edge(int src, int dest) { this.src = src; this.dest = dest; } }; // class to represent a graph object class Graph { // A list of lists to represent adjacency list List<List<Integer>> adj = new ArrayList<>(); // Constructor to construct graph public Graph(List<Edge> edges) { // allocate memory for adjacency list for (int i = 0; i < edges.size(); i++) { adj.add(i,...
I need help with todo line please public class LinkedList { private Node head; public LinkedList() { head = null; } public boolean isEmpty() { return head == null; } public int size() { int count = 0; Node current = head; while (current != null) { count++; current = current.getNext(); } return count; } public void add(int data) { Node newNode = new Node(data); newNode.setNext(head); head = newNode; } public void append(int data) { Node newNode = new Node(data);...
Help !! I need help with Depth-First Search using an undirected graph. Write a program, IN JAVA, to implement the depth-first search algorithm using the pseudocode given. Write a driver program, which reads input file mediumG.txt as an undirected graph and runs the depth-first search algorithm to find paths to all the other vertices considering 0 as the source. This driver program should display the paths in the following manner: 0 to ‘v’: list of all the vertices traversed to...
Q) Modify the class Linked List below to make it a Doubly Linked List. Name your class DoublyLinkedList. Add a method addEnd to add an integer at the end of the list and a method displayInReverse to print the list backwards. void addEnd(int x): create this method to add x to the end of the list. void displayInReverse(): create this method to display the list elements from the last item to the first one. Create a main() function to test...
Hello, i am working on java program which implements Graph as an adjacency list structure. code is the implementation of RailNetwork. i need help to change the code so it could hold String instead of integers. so, for example, Station "Station name" is connected to "Station name" and also i need to add class edge which basically will be a direction for those give stations. so the output will be like "Station name" is connected to "Station name" with "this...
When compiling the LinkedList and Iterator class, the following error is being produced: Note: LinkedList.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details. Any suggestions? public class LinkedList<T> { Node<T> itsFirstNode; Node<T> itsLastNode; private int size; public LinkedList() { itsFirstNode = null; itsLastNode = null; size = 0; } public Iterator<T> getIterator() { return new Iterator(this); } // THIS WILL NEED...
In JAVA Write a method which performs Dijkstra's algorithm on a Graph from a given stating node. It should return a Map containing the shortest distances to each node. You may need to make your own edge class as described in the tutorial to handle weights. public static Map<V.Double diikstra(Graph<V, Es graph, V start)t H
Given a singly-linked list interface and linked list node class, implement the singly-linked list which has the following methods in Java: 1. Implement 3 add() methods. One will add to the front (must be O(1)), one will add to the back (must be O(1)), and one will add anywhere in the list according to given index (must be O(1) for index 0 and O(n) for all other indices). They are: void addAtIndex(int index, T data), void addToFront(T data), void addToBack(T...
