WebApr 22, 2024 · this.head = newNode; Inserting a node at the end of the singly linked list. In this case, a new node is added at the end of the list. To implement this operation we will have to traverse through the list to find the tail node and modify the tail’s next pointer to point to the newly created node instead of null.. Initially, the list is empty and the head … WebNow we will create a simple doubly linked list with three items to understand how this works. In the above code, one, two, and three are the nodes with data items 1, 2, and 3 respectively. For node one: next stores the address of two and prev stores null (there is no node before it) For node two: next stores the address of three and prev stores ...
