Question
In a doubly linked list, which condition indicates that the list is empty?head is NULLhead->next is NULLhead->prev is NULLhead->next and head->prev are NULL
Solution
In a doubly linked list, the list is considered empty if the head is NULL. This is because the head pointer points to the start of the list. If it is NULL, it means there are no elements in the list. The conditions head->next is NULL, head->prev is NULL, or head->next and head->prev are NULL are not sufficient to indicate that the list is empty, as these could also be true if there is only one element in the list.
