Delete the node at a given position in a linked list and return a reference to the head node. The head is at position 0. The list may be empty after you delete the node. In that case, return a null value.ExampleAfter removing the node at position , .Function DescriptionComplete the deleteNode function in the editor below.deleteNode has the following parameters:- SinglyLinkedListNode pointer llist: a reference to the head node in the list- int position: the position of the node to removeReturns- SinglyLinkedListNode pointer: a reference to the head of the modified listInput FormatThe first line of input contains an integer , the number of elements in the linked list.Each of the next lines contains an integer, the node data values in order.The last line contains an integer, , the position of the node to delete.Constraints, where is the element of the linked list.Sample Input8206219741593Sample Output20 6 2 7 4 15 9ExplanationThe original list is . After deleting the node at position , the list is .

Given a doubly Linked list and a position. The task is to delete a node from a given position (position starts from 1) in a doubly linked list and return the head of the doubly Linked list.

Given pointer to a node X in a singly linked list. Only one pointer is given, pointer to head node is not given, can we delete the node X from given linked list?

What is the correct sequence of steps to delete a node at the head of a linked list? Question 27Select one: 1. Update the head pointer to point to the next node, 2. Free the memory allocated to the head node, 3. Return the updated linked list 1. Update the next pointer of the head node to null, 2. Free the memory allocated to the head node, 3. Update the head pointer to point to the next node 1. Free the memory allocated to the head node, 2. Update the head pointer to point to the next node, 3. Return the updated linked list

How is the deletion of a node at the end of a Doubly Linked List different from a Singly Linked List?a)It does not require any pointer update.b)It involves updating two pointers.c)It requires traversing the entire list.d)It requires finding the middle of the list

Given a pointer to the head of a linked list, insert a new node before the head. The value in the new node should point to and the value should be replaced with a given value. Return a reference to the new head of the list. The head pointer given may be null meaning that the initial list is empty.Function DescriptionComplete the function insertNodeAtHead in the editor below.insertNodeAtHead has the following parameter(s):SinglyLinkedListNode llist: a reference to the head of a listdata: the value to insert in the field of the new nodeInput FormatThe first line contains an integer , the number of elements to be inserted at the head of the list.The next lines contain an integer each, the elements to be inserted, one per function call.ConstraintsSample Input5383484392975321Sample Output321975392484383ExplanationIntially the list in NULL. After inserting 383, the list is 383 -> NULL.After inserting 484, the list is 484 -> 383 -> NULL.After inserting 392, the list is 392 -> 484 -> 383 -> NULL.After inserting 975, the list is 975 -> 392 -> 484 -> 383 -> NULL.After inserting 321, the list is 321 -> 975 -> 392 -> 484 -> 383 -> NULL.
