为甚么不对，如何该，：
Status ListInsert_DuL(DuLinkList &L,int n)
{
    DuLNode *p,*s;
    if(!L)  return ERROR;
    ElemType e;
    s=(DuLNode *)malloc(sizeof(DuLNode));
    if(!s)  return ERROR;
    if(n<=0)  return ERROR;
    cin>>e;
    s->data=e;
    s->next=L->next;
    L->next=s;
    s->prior=L;
    for(int i=1;i<n;i++){
            cin>>e;
            s=(DuLNode *)malloc(sizeof(DuLNode));
            s->data=e;
            p=L;
            while(p->next&&(p->next->data)<=(s->data))
                   p=p->next;
            s->prior=p;
            p->next=s;
            s->next=p->next;
            p->next->prior=s;   
        }
    return OK;
}
