NKOJ 1040: The Tower of Babylon
这是题目的原文,题目的分析和源码在后面
Perhaps you have heard of the legend of the Tower of Babylon. Nowadays many details of this tale have been forgotten. So now, in line with the educational nature of this contest, we will tell you the whole story:
The babylonians had n types of blocks, and an unlimited supply of blocks of each type. Each type-i block was a rectangular solid with linear dimensions (xi, yi, zi). A block could be reoriented so that any two of its three dimensions determined the dimensions of the base and the other dimension was the height.
They wanted to construct the tallest tower possible by stacking blocks. The problem was that, in building a tower, one block could only be placed on top of another block as long as the two base dimensions of the upper block were both strictly smaller than the corresponding base dimensions of the lower block. This meant, for example, that blocks oriented to have equal-sized bases couldn't be stacked.
Your job is to write a program that determines the height of the tallest tower the babylonians can build with a given set of blocks.

Windows里面常见的文件操作,如果文件夹里面有很多的内容,比如n个GB大小,那么在命令行下面去做会比较快的。
1.删除一个文件夹以及里面的所有内容。
RMDIR /S /Q [Your directory path here]
2.拷贝一个文件夹以及里面所有的内容到一个新的路径。
XCOPY [old path] [new path] /E /I /Q /H /K
