在循环双链表的p所指结点之后插入s结点的操作是( )
A: p->next=s; s->pre=p; p->next->pre=s; s->next=p->next;
B: p->next=s; p->next->pre=s; s->pre=p; s->next=p->next;
C: s->pre=p; s->next=p->next; p->next->pre=s; p->next=s;
D: s->pre=p; s->next=p->next; p->next=s; p->next->pre=s;
A: p->next=s; s->pre=p; p->next->pre=s; s->next=p->next;
B: p->next=s; p->next->pre=s; s->pre=p; s->next=p->next;
C: s->pre=p; s->next=p->next; p->next->pre=s; p->next=s;
D: s->pre=p; s->next=p->next; p->next=s; p->next->pre=s;
举一反三
- 若已建立以下链表结构,指针p、s分别指向如图所示结点。 则不能将s所指结点插入到链表末尾的语句组是______。 A: p=p->next; s ->next=p; p->next=s; B: s ->next='\0'; p=p->next; p->next=s; C: p=p->next; s ->next=p->next; p->next=s; D: p=(*p).next; (*s ).next=(*p).next; (*p).next=s;
- 在一个链表中,要把s所指的一个结点插入到p所指的一个结点后面去,正确的语句是: A: s->next=p->next; p->next=s; B: s->next=p; p->next=s; C: s->next=p¬->next; p=s; D: p->next=s; s->next=p;
- 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;
