链栈S的栈顶指针为top,不能执行出栈操作的是()
A: p=S->top;S->top=p->next;
B: p=S->top;S->top=p;
C: p=S;S->top=p->next;
D: p=S->top;S->top=p->next->next;
A: p=S->top;S->top=p->next;
B: p=S->top;S->top=p;
C: p=S;S->top=p->next;
D: p=S->top;S->top=p->next->next;
举一反三
- 链栈S的栈顶指针为top,不能执行p结点入栈操作的是() A: S->top=p; B: p->next=S->top;S->top=p; C: p->next=S->top;S->top=p->next; D: p=S->top;S->top=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;
- 在循环双链表的p所指结点后插入s所指结点的操作是( )。 A: s->prior=p; s->next=p->next; p->next=s; p->next->prior=s; B: p->next=s; p->next->prior=s; s->prior=p; s->next=p->next; C: p->next=s; s->prior=p; p->next->prior=s; s->next=p->next; D: s->prior=p; s->next=p->next; p->next->prior=s; p->next=s;
- 已知带头结点的链栈top,则元素x对应的新结点s进栈操作的语句是() A: top->next=s;s->next=top->next; B: s->next=top->next;top->next=s; C: s->next=top;top=s; D: top=s;s->next=top;
