Consider a single-linked list of numbers. Write an algorithm to delete a node Before a certain node. The algorithm ask user to input a number and then searches the linked list. If such a node with input value is found algorithm deletes the previous node, otherwise, it reports that such a node is not found.
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. Note: Files Ch20_Ex21Data.txt and Ch20_Ex4Data.txt contain node data that you may test your program with. minimalSpanTreeType.h : #ifndef H_msTree #define H_msTree #include <iostream> #include <fstream> #include <iomanip> #include <cfloat> #include "graphType.h" using namespace std; class msTreeType: public graphType { public: void createSpanningGraph(); //Function to create the graph and the weight matrix. //Postcondition: The graph using adjacency lists and // its weight matrix is created. void minimalSpanning(int sVertex); //Function to create a minimal spanning tree with //root as sVertex. // Postcondition: A minimal spanning…
Consider a collection of V intervals on the real line(pairs of real numbers). Such a collection defines an interval graph with one vertex corresponding to each interval, with edges between vertices if the corresponding intervalsintersect (have any points in common). Write a program that generates V random intervals in the unit interval, all of length d, then builds the corresponding interval graph.Hint: Use a BST.

You might have heard about the "Guess the Word Game", so in this game the user has to guess the letter(s) of the word one by one. There are n chances given to guess its letters where n is the number of letters in that word. You have to implement given scenario with the help of “Doubly Linked List”. Create two linkedlist, first linkedlist will be containing of complete word e.g. ELEPHANT and second linkedlist will be containing of word but having some blank letters e.g. _LEP_AN_. You have to ask user for input for every letter and insert into second linkedlist as follows: Step 1: Letter 1: Insert into second linkedlist on first place and compare 1st value of first and second linkedlist if same then go to step 2 else go to step 1 Step 2: Letter 2: Insert into second linkedlist on fifth place and compare 5th value of first and second linkedlist if same then go to step 3 else go to step 2 Step 3: Letter 3: Insert into second linkedlist on last place and compare last value of…
Given a singly linked list, reverse the list. This means you have to reverse every node. For example if there are 4 nodes, the node at position 0 will move to position 3, the node at 1 will move to position 2 and so on. You do not have to write the Node class just write what you have been asked to. You are NOT allowed to create a new list. In python language
Write a JAVA method SingleChildCount to return the number of nodes that have only one child. Test the method in BSTApp.
Create a script in python to create a graph of two user given polynomials. Your script should get a starting point,ending point, and the number of points for the graph from the user (use linearly spaced points). It shouldalso get the coefficients of each polynomial from the user. Plot the first polynomial in red and the secondpolynomial in blue. Your graph should have a legend with useful information that is in the upper centerpart of the graph. Finally, your graph should have a proper title and proper labels on each axis.
Our main objective is to implement breadth-first-search (BFS) to print the vertices of a graph G. To get the full grade, you must annotate your code (i.e., write relevant comments throughout your program) and proceed as follows: Ask the user to enter the number of nodes of a graph G. Ask the user to enter the edges of G (e.g., if the user enters 3 and 5; it means that there is an edge between nodes 3 and 5). Store the graph G using an adjacency matrix. Run BFS on G, starting form node 1 (i.e., we assume here that the start node is 1). Use a queue to implement BFS. You may use the queue class from the library of the programming language you are using (so there is no need to implement your own class queue). Write a main function to test your program, and make sure BFS is visiting the vertices of G as expected.
Implement the complete code Delete that, when given an info value newElement, finds and deletes the first element with this value, if it exists. This involves also considering the four special cases listed for deleting a node from the beginning or the end of a linked list.
IN JAVA (Find paths)Define a new class named UnweightedGraphWithGetPath that extends UnweightedGraph with a new method for finding a path between two vertices with the following header:public List getPath(int u, int v);The method returns a List that contains all the vertices in a path from u to v in this order. Using the BFS approach, you can obtain the shortest path from u to v. If there isn’t a path from u to v, the method returns null. Write a test program that creates a graph for Figure 28.1. The program prompts the user to enter two cities and displays their paths. Sample RunEnter a starting city: SeattleEnter an ending city: MiamiThe path is Seattle Denver Kansas City Atlanta Miami Use https://liangpy.pearsoncmg.com/test/Exercise28_05.txt to test your code.
interval graphs at random. Think about a set of pairs of real numbers called V intervals on the real line. A collection like this produces an interval graph with a vertex for each interval and edges connecting them when they intersect (have any points in common). Create a programme that creates V randomly chosen intervals, each of length d, in the unit interval and then constructs the associated interval graph.Please use a BST.
