在一个双链表中,在p节点之后插入节点q的操作是_()
A.q->prior = p;p-> next=q;p -> next -> prior =q; q ->next = p -> next B.q ->next = p -> next;p -> next -> prior =q;p-> next=q;q->prior = p C.p-> next=q;q->prior = p;q ->next = p -> next;p -> next -> prior =q D.p -> next -> prior =q;q->prior = p;p-> next=q;q ->next = p -> next
