In a doubly linked list, what’s the “head” of a linked list?It’s the node with the pointer to the previous node equals to NULLIt’s the node with the pointer to the next node equals to NULLI don't know
Solution
In a doubly linked list, the "head" of the list is the node with the pointer to the previous node equals to NULL. This is because in a doubly linked list, each node contains a data part and two pointers, one pointing to the next node and one pointing to the previous node. The head of the list is the first node, which does not have a previous node, hence the pointer to the previous node is NULL.
