LNode* magrelist(LNode *la,LNode *lb,LNode *lc)
{
    LNode *l1,*l2;
    l1=la;
    l2=lb;
    while((l1->next!=NULL)||(l2->next!=NULL)!=NULL)
    {
        if(l1->data>l2->data)
        {
            lc->next=l1;
            lc=l1;
            l1=l1->next;
        }
        else if(l1->data==l2->data)
        {
            lc->next=l1;
            lc=l1;
            l1=l1->next;l2=l2->next;
        }
        else
        {
            lc->next=l2;
            lc=l2;
            l2=l2->next;
        }
    }
    return lc;
}
这个算法错在哪里呢?

谢谢LS,不过我希望有人指点下我的函数错在哪.
