1) Here is the structure declaration of a doubly linked list
struct dlink {
int nodeid;
struct dlink *next;
struct 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 funtion remove_element(dlink_t *rp), needs to
remove the node pointed to the 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;
