红黑树：输入：在同一目录下的redblacktree.txt文件中输入十个大于0的数值，每个数值中间用空格格开 数目可以大于十个，但是要求在源程序中改变＃define NUM 10 ，改成相应关键值各个数输出：按照先序输出红黑树，格式为：根节点。颜色（左子树。颜色，右子树。颜色），并输出此 树的黑高度，然后输入要删除的关键值，按回车后输出删除后的结果，并输出其高度。-RED-BLACK TREE : Admission : in the same directory under the file input redblacktree.txt greater than 0 10 digits each intermediate numerical grid with open spaces can be greater than the number 10, but requested change in the source# define NUM 10, the corresponding critical value into several different output : In accordance with the first sequence RED-BLACK TREE output format : nodes. Color (left subtree. Color, right subtrees. Color), and export of the black tree height and then delete the key to value, according to enter the output was the result of the deletion, and its high output.

外部排序程序，foxpro的DBF文件中某个字段的程序，特点是可以指定排序内存大小，但可以排序超级大的文件远远超出机器内存，采用快速排序加失败树合并算法，排序中会产生很多临时小文件。修改后可用于任何文件字段排序。-External sort procedure, foxpro of DBF files in a field procedure, and there is a sort of memory you can specify the size, but you can sort super large files far beyond the machine memory, the use of quick sort algorithm plus the failure of the merger tree, sorting will produce many temporary small files. The revised document can be used for any sort by that field.
