多重回滚操作的实现-The implementation of mulitple undo

书上的例子，是本人在学习过程中的作品，上传给大家学习学习-book on the case, I was in the learning process works, we upload to learn from

array.h： 安全数组 linkedlist.h： 普通表 dclinkedlist： 双向循环链表 hashtable.h： 哈希表 binstree.h： 二叉搜索树 avltree.h： AVL 树 如果要存储集合（元素不可重复）并快速查找，最佳的是 binstree.h（二叉搜索树）。 如果要存储二维或更高维的表格，最佳的是 hashtable.h（哈系表）。AVL 树的插入成本非常高（删除函数也没有实现），但 AVL 的搜索效率极高，所以适用于在程序开始前初始化程-NOTE: array.h :secure array,linkedlist.h:common table, dclinkedlist:dual cycle linkedlist, hashtable.h:hash table binstree.h:binary search tree, avltree.h: AVL tree, if you want to store set(elements no repeating) and to lookup it swiftly,best is binstree.h(binary search tree).if you want to store two dimensions s or more dimensions s table,best hashtable.h(hash table).the cost of AVL tree s insertion is very high(delete function is not completed),but effiency of AVL tree s search is very high,so it is the same with initialize programme before beginning programme.
