PowerBuilder应用开发经验及示例

phpMySQLAutoBackup能自动备份mysql数据库，并将导出的数据库（数据与结构）压缩成gzip格式然后用email通知你。phpMySQLAutoBackup能够按设置每天/周定时备份，选择不同的表格来备份，当备份表格时,可以设置备份开始和结束的行数，以便让你能够有选择的备份一个巨大表格(数百万条数据)任一部分。 -phpMySQLAutoBackup can automatically backup mysql database, and export the database (data and structure) and then compressed into gzip format to inform you by email. phpMySQLAutoBackup able to set up a day/week timer backup, choose a different form to back up, when the back-up form, you can set the beginning and end of back-up the number of rows, so that you can choose to backup a large table (millions of data) any part of.

中序遍历输出二叉树 输出二叉树的叶子树 输出二叉树的节点数-which preorder output binary tree output binary tree leaf tree output binary tree nodes

字典序问题：在数据加密和数据压缩中常需要对特殊的字符串进行数字编号。给定的字母表 A 由 26 个小写英文字母组成 A={a,b,…,z}。该字母表产生的升序字符串是指字符串中字母按照从左 到右出现的次序与字母在字母表中出现的次序相同，且每个字符最多出现1 次。例如， a,b,ab,bc,xyz等字符串都是升序字符串。现在对字母表A 产生的升序字符串按照字典序排列 并编号如下。-Lexicographic problem
