很久以前做的一道思博题了,今天来补一补. 大致题意:在一个\(n*m\)的矩阵内填整数,数字在\([1,k]\)范围内.矩阵中某格的数为great number当且仅当与它同行同列的数字都严格比它小.记\(A_g\)为矩阵中恰有\(g\)个great number的填数方案数,求\(\sum_{g=0}^{nm}(g+1)\cdot A_g\).(\(n,m,k\le200\)) 首先我们可以看出,上界必定是\(min(n,m)\),这个不解释了吧 而又有一个性质,\(\sum_{g=0}^{m…

Excel导入及导出问题产生: 从接触.net到现在一直在维护一个DataTable导s出到Excel的类,时不时还会维护一个导入类.以下是时不时就会出现的问题: 导出问题: 如果是asp.net,你得在服务器端装Office,几百M呢,还得及时更新它,以防漏洞,还得设定权限允许ASP.net访问COM+,听说如果导出过程中出问题可能导致服务器宕机. Excel会把只包含数字的列进行类型转换,本来是文本型的,它非要把你转成数值型的,像身份证后三位变成000,编号000123会变成123,够智能吧…

解决思路: 1.找个可用的Aspose.Cells(有钱还是买个正版吧,谁开发个东西也不容易): 2.在.Net方案中引用此Cells: 3.写个函数ToExcel(传递一个DataTable),可以另写个SetCellStyle的函数专门给各列设置样式. 4.在按钮的Click事件中调用此ToExcel()即可. 注:想更详细了解的到Aspose网站去,那里有很多在线文档,够你看的了.也可以下载个Demo程序研究. 部分代码贴在这里,代码还有需要改进的地方,暂时这么用着,给自己以后方便查找,再…
