Question
How is the last node of a Doubly Linked List identified?a)It contains a special value indicating the end.b)It points to NULL in the previous field.c)It points to NULL in the next field.d)It points to the first node.
Solution
The last node of a Doubly Linked List is identified by "c) It points to NULL in the next field." In a Doubly Linked List, each node contains a data part and two pointers, one pointing to the next node and another pointing to the previous node. The last node in this list has its next pointer pointing to NULL, indicating the end of the list.
