零件切割问题： 给定一块宽度为W的矩形板，矩形板的高度不受限制。现需要从板上分别切割出n个高度为hi，宽度为wi的矩形零件。切割的规则是零件的高度方向与矩形板的高度方向保持一致。问如何切割使得所使用的矩形板的高度h最小？ 任给一个输入实例，能输出切割所需要的实际高度并能用图形演示切割的过程-cutting parts : a given width of the rectangular plate W, the height of rectangular plate unrestricted. Need from the board is cutting out respectively n height of the hi, wi width of the rectangular parts. Cutting parts to the rules of the height of the rectangular plate with a high degree of consistent direction. Asked how cutting makes use of the rectangular plate height h minimum? As an input for example, will cut output by the needs of the high and can be used graphic demonstration of the cutting proce

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.
