Another friend implemented a queue as a linked list with only a head pointer (no tail node). She said this made performance of all functions (insert, remove, search, and update) categorically equal to a queue as a linked list with a head and a tail node. Is she correct? Why or why not?

- I need a reference page for this question that was answered below. What is the difference between a singly-linked list and a doubly-linked list? In what situation would you use a singly-linked list over a doubly-linked list? In what situation would you use a doubly-linked list over a singly-linked list? If a node is in a linked list with N nodes, how many nodes will be traversed during a search for the node? Explain the best- and worst-case search scenarios. Explain why a singly-linked list defines a RemoveAfter() function, while a doubly-linked list defines a Remove() function. Could a RemoveAfter() function also be defined for a doubly-linked list? Explain why or why not. Could a Remove() function also be defined for a singly-linked list? Explain why or why not.Question 42 What makes implementing a queue with a Doubly Linked List relatively easier than implementing a queue with a typical array, where all elements stay in adjacent locations? There's no need to explicitly shift the elements of a Linked List to the front, as there would be in an array. There's no need to keep track of how many elements are present, as there would be in an array. There is no advantage to using a Linked List implementation over an array implementation. There's no need to keep track of a front and a back, as there would be in an array.Write the code to delete a node in the middle of a list implemented as a linked list with the dummy node (see Exercise 3). Compare your answer with the answer to Exercise 3. Are they the same? What do you conclude? Does the dummy node simplify the operation on the list? How?
- Consider the following scenario: a software creates and manipulates a linked list, like follows:The software would normally maintain track of two special nodes, which are as follows: Explanation of how to utilise the null reference in the node of the linked list in two frequent situations?Is it possible to implement a sorted linked list using a DLL? What is the advantage of using a DLL versus a single linked list? Back up your point with a real example or application.The specifications for the Sorted List ADT state that the item to bedeleted is in the list.1. Rewrite the specification for DeleteItem so that the listis unchanged if the item to be deleted is not in the list.2. Implement DeleteItem as specified in (a) using anarray-based implementation.3. Implement DeleteItem as specified in (a) using alinked implementation.4. Rewrite the specification for DeleteItem so that allcopies of the item to be deleted are removed if they exist.5. Implement DeleteItem as specified in (d) using anarray-based implementation.6. Implement DeleteItem as specified in (d) using alinked implementation.

Explain why a singly-linked list defines a RemoveAfter() function, while a doubly-linked list defines a Remove() function. Could a RemoveAfter() function also be defined for a doubly-linked list? Explain why or why not. Could a Remove() function also be defined for a singly-linked list? Explain why or why not.ANSWER ASAP. C++ LANGUAGE ONLY. (NOT C, NOT JAVA, NOT C#) CPP ONLY Using the double-ended linked list C language syntax code below, convert it into C++ and use it as the base. Modify the provided program into the ff: create a new class named student_queue. and then.. Implement the following methods for the class: front() - returns the pointer to the front element of the queue back() - returns the pointer to the back element of the queue push() - allocates memory for a new node and connects it to the existing queue pop() - retrieves the oldest node in the queue, copies the data to a structure, and frees up the memory from the queue empty() - returns 1 or 0 depending on whether the queue is empty or not size() - returns the number of elements in the queue Program code: #include <stdio.h>#include <stdlib.h>typedef struct se_list_type {int num;struct se_list_type* prev;struct se_list_type* next;} se_list;int main() {// Start the listse_list* head = NULL;se_list* cur =…By using Java, Give the implementation of a function that displays elements greater that a given value from a binary search tree (BST) implemented using linked list.
- Suppose there are two singly linked lists both of which intersect at some point and become a single linked list. The head or start pointers of both the lists are known, but the intersecting node is unknown. Also, the number of nodes in each of the list before they intersect are unknown and both the list may have it different. List1 may have n nodes before it reaches intersection point and List2 might have m nodes before it reaches intersection point where m and n may be m = n, m > n or m < n. Give an algorithm for finding the merging point. Hints: A brute force approach would be to compare every pointer in one list with every pointer in another list. But in this case the complexity would be O(mn)Please help with this. I really needed help.Please fast...... avoid plagiarism Explain in your own words the steps necessary to add a value to the tail of a single-ended, singly-linked list. The list should have a reference (pointer) to its head and should terminate in nullptr/NULL/none. Make sure you deal with all possible cases.
