the number of edges in a complete 2 of 2 undirected graph of 80 vertices is.? Select one: a. exactly equals 3160 b. None c. less than or equals 3160 d. less than or equals 6320 e. exactly equals 6320 Assume that you have a doubly link list. Pointer x is pointing to the last node in the link list and pointer y is pointing to before the last node. which of the following will remove the node pointed by x from the list? Select one: O a. delete x; b. y->prev->next = y->next; X->prev= y->prev; delete x; O C. X->prev->next = x->next; y->prev= x->prev; delete x; O d. x->next = y; y->prev = x->prev; delete x;
Integer numSize is read from input. ArrayList colorsList contains numSize strings read from input. Complete the enhanced for loop to output each value in colorsList. Ex: If the input is: 5 blue red violet green orange then the output is: blue is available red is available violet is available green is available orange is available import java.util.Scanner;import java.util.ArrayList; public class Colors { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); ArrayList<String> colorsList = new ArrayList<String>(); int numSize; int i; numSize = scnr.nextInt(); for (i = 0; i < numSize; ++i) { colorsList.add(scnr.next()); } for (/* Your code goes here */) { System.out.println(colorVal + " is available"); } }} java please
3. Implement both Prim's algorithm and Kruskal's algorithm. Compare therunning times of your programs on a set of "random" graphs.4. Write a program to find all the connected components of a graph.5. Consider the following list of integers: [1,2,3,4,5,6,7,8,9,10]. Show how this list is sorted by the following algorithms:• bubble sort• selection sort• insertion sort• shell sort (you decide on the increments)• merge sort• quick sort (you decide on the pivot value
USE PYTHON No imports can be used input the txt file and find the shortest path that begins and ends at the vertex with label 1. This path must have at least one edge. Your answer should be a list containing the vertices in the path starting at 1. Shortest refers to the path with the fewest number of vertices. The Txt file is below 1 21 82 32 52 122 92 163 23 104 14 105 25 166 86 187 67 208 48 69 29 59 1710 310 510 20 ... so here it should be(1, 8) -> (8, 4) --> (4, 1)
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.
Define a collection “ArrayList” to store the students' names. Use a loop to take 5 students’ names from the user and store them in the collection. Add two student names to the collection and remove the last name in the list. Insert a student name in third place in the collection. Sort the names alphabetically. Ask the user to enter a student name and search for it in the collection and prints the result as “Found” or “Not Found”. Print the whole collection using the enhanced for loop. (java)

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.
A singly linked circular list is a linked list where the last node in the list points to the first node in the list. A circular list does not contain NULL pointers. A good example of an application where a circular linked list should be used is an item in the shopping cart In an online shopping cart, the system must maintain a list of items and must calculate the total bill by adding the amount of all the items in the cart, Implement the above scenario using a Circular Link List of data structure in C++ Programming. Do Following: First create a class Item having id, name, price, and quantity provide appropriate methods and then Create Cart/List class which holds an items object to represent total items in the cart and next pointer Implement the method to add items in the array, remove an item and display all items. Now in the main do the following Insert Items in the list Display all items. Traverse the link list so that each item's bill gets calculated (by multiplying quantity with…
You have been given a linked list of integers. Your task is to write a function that deletes a node from a given position, 'POS'.Note :Assume that the Indexing for the linked list always starts from 0. If the position is greater than or equal to the length of the linked list, you should return the same linked list without any change.Illustration :The following images depict how the deletion has been performed.Image-I :Alt txt Image-II :Alt txt Input format :The first line contains an Integer 'T' which denotes the number of test cases or queries to be run. Then the test cases follow. The first line of each test case or query contains the elements of the linked list separated by a single space. The second line of each test case contains the integer value of 'POS'. It denotes the position in the linked list from where the node has to be deleted. Remember/Consider :While specifying the list elements for input, -1 indicates the end of the singly linked list and hence, would never be a list…
Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print: 7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = courseGrades.length - 1. import java.util.Scanner; public class CourseGradePrinter {public static void main (String [ ] args) {Scanner scnr = new Scanner(System.in);final int NUM_VALS = 4;int [ ] courseGrades = new int[NUM_VALS];int i; for (i = 0; i < courseGrades.length; ++i) {courseGrades[i] = scnr.nextInt();} /* Your solution goes here */ }}
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
