著名的LZW压缩和解压的C++实现，通过hash出来的动态字典可对文本或图片进行压缩和解压，有不错的压缩比。-Well-known LZW compression and decompression of the C++ Achieve, through the dynamic dictionary hash out of text or picture compression and decompression, a good compression ratio.

基于LZW字典编码的压缩解压算法，动态建立编译表并用哈希表结构存储索引。-Dictionary-based LZW compression decompression coding algorithm, dynamic compilation table set up and use the hash table structure to store the index.
