实例有关说明： 数据源：本实例使用的数据源在本章实例MyOdbcSmpl目录中，数据源为ACCESS数据源，数 据文件为Mydb.mdb。请根据本章2.4.1创建ODBC数据源中所指示的ODBC数据源管 理器（ODBC32.exe）来创建和配置数据源MyDB（也可以命名为其他名称）。 执行结果：本章实例的执行结果MyOdbcSmpl目录中的可执行文件MyOdbcSmpl.exe。在数据 源中选择刚配置的MyDB，在数据表或视图中选择要查询的表或视图，选择查询的 列，如果有查询条件，请在查询条件中输入，最后确定是否输出显示查询结果， 缺省为显示，单击“执行”按钮，执行查询并显示查询结果，在SQL语句框中显 示执行的查询。-Note : Data Source : The data used by the examples in this chapter source directory MyOdbcSmpl example, ACCESS data source for data sources, data files for Mydb.mdb. Requests under this chapter 2.4.1 create ODBC data source as directed by the ODBC Data Source Manager (ODBC32.exe) to create and configure data sources MyDB (also named other names). Outcome : examples of this chapter MyOdbcSmpl results of the implementation of the directory MyOdbcSmpl.exe executable files.

问题描述： 给定n个石子，其重量分别a1,a2,a3...an,要求将其划分成m份，每一份的划分费 义为这份石了中最大重量与最小重量的差的平方。总划分费用等丁m份划分费用之和。 编程任务 对于给定的n个石子，求一种划分方案，使得总划分费用最小。-Description of the problem: Given n-stones, its weight, respectively a1, a2, a3 ... an, asked that it be divided into m copies, each of the division of costs defined as the weight of the stone of the largest and the smallest weight difference the square. Small m the total costs were divided into the sum of the cost. Programming tasks for a given n-stones, seek a kind of division, making the total cost of the smallest division.
