16字节字符串压缩成12字节字符串算法，有压缩和解压的算法(16-byte string into a 12-byte string compression algorithm, compression and decompression algorithms)

这是一个基于LZARI算法的数据压缩的类.Haruhiko Okumura 于1989年7月4日用C语言写实现了这个算法.但是上面用到了一些全局或静态的变量,在MFC下用起来很不方便.作者把它改写成了一个C++类,使它可以方便的压缩和解压缩。(LZARI algorithm based on the type of data compression. Haruhiko SAP in 1989, July 4 C language daily wrote realization of this algorithm. But above uses some static or global variables, using the MFC which are very convenient. Authors rewrite it became a category C, it can be to facilitate the compression.)

bnpts点云文件 进过压缩处理 大约100000个点(bnpts)

说明：  利用gzip.dll解压http请求返回的内容。内附gzip.dll。参考网上资料自己写的VB6工程源码。自己编译EXE的时候注意把gzip.dll释放到exe所在目录。(Use gzip.dll to decompress the content returned by HTTP request. Gzip.dll is attached. Refer to the VB6 project source code written by myself.)

香农编码的C++实现。原理说明以及源代码。(The Shannon coding C++. Principle of instructions and source code.)

Huffman编码，使用哈弗曼树生成前缀码，把输入的字符编码并把原字符解码(Huffman code and decode)

RLE是一个压缩的算法，里面有算法的C++程序实现。(RLE is a compression algorithm, there are algorithms C++ program)

输入两个正整数m和n，求其最大公约数和最小公倍数(Enter two positive integers m and n, can seek the common denominator and least common multiple)
