Problem Statement23hr leftGiven a linked list, write a program to insert or delete nodes from the beginning.Input:n = 5[6, 5, 4, 3, 2, 1]Notice that here, we are inserting each element from the beginning. Hence when you insert a new element, the list becomes newEle + OldLL.For example, if you add 3 to [4, 5, 6] then it becomes [3, 4, 5, 6].Output:[1, 2, 3, 4, 5, 6] -> after inserting elements [2, 3, 4, 5, 6] -> after deleting the beginning elementConstraint:If the linked list is empty, print an empty space.
Solution
To solve the given problem, we need to write a program that can insert or delete nodes from the beginning of a linked list. The input for this program is a number 'n' and a list of elements. The number 'n' represents the number of elements in the list, and the list contains the elements of the linked list.
To insert a new element at the beginning of the linked list, we need to add the new element before the existing elements. This means that the new element will become the first element of the linked list. For example, if we add the element 3 to the list [4, 5, 6], the new list will be [3, 4, 5, 6].
To delete the first element of the linked list, we simply remove the first element from the list. This means that the second element will become the new first element. For example, if we delete the first element from the list [1, 2, 3, 4, 5, 6], the new list will be [2, 3, 4, 5, 6].
The output of the program should be the final linked list after performing the insertions and deletions.
There is one constraint to consider: if the linked list is empty, we should print an empty space.
To implement this program, we can use a programming language that supports linked lists and provides functions for inserting and deleting elements from the beginning of the list.

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.

Linked List Operations: Traverse, Insert and DeleteTraversal - access each element of the linked list.Insertion - adds a new element to the linked list.Deletion - removes the existing elements.Search - find a node in the linked list.Sort - sort the nodes of the linked list.
