Consider the following structure declaration of a doubly linked list:
struct dlink
{
int nodeid;
dlink *next;
dlink *prev;
} dlink t;
A pointer of the head of the linked list is maintained as a global variable, whose
definition is
dlink t *head;
The function remove element(dlink t *rp) defined below needs to remove the
node pointed to rp and adjust the head. The first node’s prev and the last node’s
next are NULL.
remove element(dlink t *rp)
{
rp->prev->next = rp->next;
rp->next->prev = rp->prev;
if(head == rp)
head = rp->next;
}
Explain whether the function remove element() works properly or not.

The function `remove_element()` works properly for removing a node from a doubly linked list and adjusting the head pointer under certain conditions. However, there are scenarios where this function may encounter issues:
