在循环双链表的p所指向结点之后插入结点s的操作步骤是（ ）。 A: p->next=s; s->prior=p; p->next->prior=s; s->next=p->prior; B: p->next=s; p->prior->next=s；s->prior=p; s->next=p->next; C: s->prior=p; s->next=p->next; p->next=s; p->next->prior=s; D: s->prior=p; s->next=p->next; p->next->prior=s; p->next =s;

在循环双链表的P所指节点之后插入s所指节点的操作是( ) A: p->next=s; s->prior=p; p->next->prior=s; s->next=p->next; B: p->next=s; p->next->prior=s; s->prior=p; s->next=p->next; C: s->prior=p; s->next=p->next; p->next=s; p->next->prior=s; D: s->prior=p; s->next=p->next; p->next=s;p->next->prior=s;

在循环双链表的P所指节点之后插入s所指节点的操作是( ) A: p->next=s; s->prior=p; p->next->prior=s; s->next=p->next; B: p->next=s; p->next->prior=s; s->prior=p; s->next=p->next; C: s->prior=p; s->next=p->next; p->next=s; p->next->prior=s; D: s->prior=p; s->next=p->next; p->next=s;p->next->prior=s;

在非空双向链表中,若要在p结点后面插入s结点,正确的语句序列是( )。 A: p->next=s ;s->prior=p;p->next->prior=s ;s->next=p->next; B: p->next->prior=s;p->next=s;s->prior=p;s->next=p->next; C: s->prior=p;s->next=p->next;p->next=s;p->next->prior=s ; D: s->next=p->next;p->next->prior=s ;s->prior=p;p->next=s;

在循环双链表的p所指的结点之前插入s所指结点的操作是 （ ） A: p->;prior = s；s->;next = p；p->;prior->;next = s；s->;prior = p->;prior； B: p->;prior = s；p->;prior->;next = s；s->;next = p；s->;prior = p->;prior； C: s->;next = p；s->;prior = p->;prior；p->;prior = s；p->;prior->;next = s； D: s->;next = p；s->;prior = p->;prior；p->;prior->;next = s；p->;prior = s；
