双向循环链表节点：数据域+指针域指针域：一个指针指向前一个同类型节点，另一个指针指向后一个同类型节点（1）设计节点struct db_node{int data;struct db_node * prev;struct db_node * next;};（2）创建空链表//创建了一个只有头节点的双向循环链表，返回头节点的地址struct db_node * create_db_list(void){struct db_node * phead = (struct db_node *)malloc(sizeof(struct db_node));if(phead == NULL)exit(-1);else{phead->next = phead;phead->prev = phead;}return phead;}（3）制造新节点//制造新节点，返回新节点的地址struct db_node * make_db_node(int value){struct db_node * pnew = (struct db_node *)malloc(sizeof(struct db_node));if(pnew == NULL)printf("malloc failed! ");else{pnew->data = value;pnew->next = NULL;pnew->prev = NULL;}return pnew;}（4）插入节点//把pnew指向的节点插入到头节点的前面，也就是整个链表的末尾bo

篮球赛抽签系统，先输入球队数，由随机函数在1-N抽取一个数，作为初始密码，出列第一支球队，然后根据各队输入本队密码，利用joseph环，使每次出列的球队密码作为新的密码，直到所有球队出列，即可确定分组顺序-Basketball lottery system, first enter the team number by the random function in the 1-N taken a number, as the initial password, the first teams out of the column, and then each team enter the team password, using joseph ring, so that each second team out of the column as a new password password, until all the teams out of the column, you can determine the packet sequence

使用链表数据结构算法，将中缀表达式转变为后缀表达式。-The use of linked list data structure algorithms, will be made up of expressions into expressions suffix.
