huffman编码，一种压缩与解压缩的程序，仅供大家参考。

字符串的压缩与解压，输入一字符串文件，压缩后得一文件，在经解压得原文件。大家一起分享。-string compression and decompression, the importation of a string, in a compressed file, after decompression in the original document. To share with everyone.

Zip文件的加压解压-Zip file compression of decompression

zip解压源码.-zip unpacked source.

按键扫描驱动程序 写的还不错，希望大家看看阿！第一次上这个网，才知道这个网好好啊！-button scanning driver wrote was pretty good, we hope to see A! First on the net, before we know the net good ah!

自适应的霍夫曼编码是一种扩展的熵编码方法，取得了更高的编码效果。这是几种自适应霍夫曼编码的实现方法。希望对大家有用。-adaptive huffman coding is an extended coding method ,which can get more efficient compression ratio. this is kinds of adaptive huffman coding methods. i hope it will be useful for people who research huffman code.

通信中的压缩、解压缩。利用相对编码的原理，进行前后相减。（编程背景为温室温度测量，限定在正负50以内）。已经编译通过。-Communication compression, decompression. The principle use of the relative encoding, carried out before and after the subtraction. (Programming background greenhouse temperature measurement, limited to within plus or minus 50). Has been compiled through.
