Data manipulation tasks frequently include insert a node at a specific position in linked list. We must first determine the position in a linked list where we wish to insert the new node. After selecting the place, we must search the attached list for the node that precedes the required position. So, to add a new node to the list, we may update the pointers of the old node and the new node. HackerRank has given us this Problem to Solve.
