在一个双链表中,在*p节点之后插入节点*q的操作是()。
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;
正确答案:q ->next = p -> next;p -> next -> prior =q;p-> next=q;q->prior = p;
