快速排序
快速排序是递归的思路谈起来是很简单的:(1)当待排元素S个数为1的时候,什么也不做。(2)在待排元素S中取一个元素作为枢纽pivot。(3)将待排元素分成三份:小于pivot的元素S1、pivot它自己、大于pivot的元素S2。(4)对小于pivot的元素S1进行快速排序,对大于pivot的元素S...

《BI那点儿事》数据流转换——透视
这个和T-SQL中的PIVOT和UNPIVOT的作用是一样的。数据透视转换可以将数据规范或使它在报表中更具可读性。通过透视列值的输入数据,透视转换将规范的数据集转变成规范程度稍低、但更为简洁的版本。例如,在列有客户名称、产品和购买数量的规范的 Orders 数据集中,任何购买多种产品的客户都有多行,...
