循环链表的节点对换和删除：
//双向循环
list_node* earse(list_node* node)
{
// if(node == rear) return node->next; //对于头节点可判断也可不判断。最好加上
list_node* next = node->next;
next->prev = node->prev;
node->prev->next = next;
delete node;
retrun next;
}
//单项循环
list_node* earse(list_node* node)
{
// if(node == rear) return node->next; //对于头节点可判断也可不判断。最好加上
list_node* p = rear;
while(p->next != node) p=p->next;
p->next = node->next;
delete node;
retrun p->next;
}
