双链表结点定义如下,若要删除双链表中的中间结点(非首尾节点) p ,下面写法正确的是( )。

struct Node {
    int val;
    Node* prev;
    Node* next;
};

A.

p->prev->next = p->next;
p->next->prev = p->prev;
delete p;

B.

p->next->prev = p->next;
p->prev->next = p->prev;
delete p;

C.

p->prev = p->next;
p->next = p->prev;
delete p;

D.

p->next->next = p->prev;
p->prev->prev = p->next;
delete p;

{{ select(1) }}

• A
• B
