How do you insert a new node at the beginning of a singly linked list?Group of answer choicesCreate a new node and adjust the next pointer of the new node to point to the current head nodeCreate a new node and set its next pointer to nullCreate a new node and adjust the previous pointer of the new node to point to the current head nodeCreate a new node and adjust the previous pointer of the current head node to point to the new node

Given the pointer to the head node of a linked list and an integer to insert at a certain position, create a new node with the given integer as its attribute, insert this node at the desired position and return the head node.A position of 0 indicates head, a position of 1 indicates one node away from the head and so on. The head pointer given may be null meaning that the initial list is empty.Example refers to the first node in the list Insert a node at position with . The new list is Function Description Complete the function insertNodeAtPosition in the editor below. It must return a reference to the head node of your finished list.insertNodeAtPosition has the following parameters:head: a SinglyLinkedListNode pointer to the head of the listdata: an integer value to insert as data in your new nodeposition: an integer position to insert the new node, zero based indexingReturnsSinglyLinkedListNode pointer: a reference to the head of the revised listInput FormatThe first line contains an integer , the number of elements in the linked list.Each of the next lines contains an integer SinglyLinkedListNode[i].data.The next line contains an integer , the data of the node that is to be inserted.The last line contains an integer .Constraints, where is the element of the linked list..Sample Input31613712Sample Output16 13 1 7ExplanationThe initial linked list is . Insert at the position which currently has in it. The updated linked list is .

This challenge is part of a tutorial track by MyCodeSchool and is accompanied by a video lesson.You are given the pointer to the head node of a linked list and an integer to add to the list. Create a new node with the given integer. Insert this node at the tail of the linked list and return the head node of the linked list formed after inserting this new node. The given head pointer may be null, meaning that the initial list is empty.Function DescriptionComplete the insertNodeAtTail function in the editor below.insertNodeAtTail has the following parameters:SinglyLinkedListNode pointer head: a reference to the head of a listint data: the data value for the node to insertReturnsSinglyLinkedListNode pointer: reference to the head of the modified linked listInput FormatThe first line contains an integer , the number of elements in the linked list.The next lines contain an integer each, the value that needs to be inserted at tail.ConstraintsSample InputSTDIN Function ----- -------- 5 size of linked list n = 5 141 linked list data values 141..474 302 164 530 474Sample Output141302164530474ExplanationFirst the linked list is NULL. After inserting 141, the list is 141 -> NULL.After inserting 302, the list is 141 -> 302 -> NULL.After inserting 164, the list is 141 -> 302 -> 164 -> NULL.After inserting 530, the list is 141 -> 302 -> 164 -> 530 -> NULL. After inserting 474, the list is 141 -> 302 -> 164 -> 530 -> 474 -> NULL, which is the final list.

In a doubly linked list, how many pointers need to be updated to insert a new node at the end? Group of answer choices3421

A linked list whose last node points back to both the head node and the previous node instead of containing the null pointer ____________

What is the correct sequence of steps to add a node at the end of a single linked list? Question 34Select one: 1. Create a new node with the given data, 2. Traverse the linked list to find the tail node, 3. Update the next pointer of the tail node to point to the new node, 4. Update the next pointer of the new node to null 1. Create a new node with the given data, 2. Update the next pointer of the new node to null, 3. Traverse the linked list to find the tail node, 4. Update the next pointer of the tail node to point to the new node 1. Traverse the linked list to find the tail node, 2. Create a new node with the given data, 3.
