实现线性表的链式存储结构—线性链表。

从文件输入一批整数，建立有序链表（升序），并完成：

查找一个指定元素

插入一个给定元素

删除一个指定元素

统计链表的长度

输出线性链表

实现链表的逆序重建-The linear form of chain store structure- linear list. Enter the number of integers from a file, to establish orderly list (ASC), and complete: Finding a specified element into a given element to delete a specified element statistical output linear chain length of chain to achieve the reverse of rebuilding list
