Question
How is the last node identified in a doubly linked list?It points to None.It has a special flag.It has a reference to the first node.It has a pointer to the previous node.
Solution
The last node in a doubly linked list is identified as the one that points to None. In a doubly linked list, each node contains a data element and two pointers that link to the previous and next node. The first node has its previous pointer pointing to None, and the last node has its next pointer pointing to None. This is how the start and end of the list are identified.
