HuffmanCode
Huffman 编码是第一个实用的无损压缩编码技术,经过了多年的不断改进,已经形成了系统的理论和方法。目前主要有两种类型的Huffman编码方式,即静态Huffman编码和动态Huffman编码。Huffman编码有着广泛的应用,但是不再是压缩算法的全部,而是被当作最终的编码方法。(Huffman coding is the first practical lossless compression coding technology, after years of continuous improvement, has formed a system of theories and methods. There are currently two types of Huffman encoding, namely, static and dynamic Huffman coding Huffman coding. Huffman coding has been widely used, but the compression algorithm is no longer all, but rather be treated as the final coding.)

hufman
哈夫曼文本压缩器,两个功能压缩文本文件和解压二进制文件。
内容为源代码,用编译器把源代码运行一遍,把需要压缩的txt文件放到和源代码同一个目录下,压缩名称输入 **.txt 压缩后的名称一定要写二进制格式的 例如 **.dat
只能解压用这个程序压缩后的文件。。
解压名 写 **.dat 解压后名称 **.txt(Huffman text compression, two text files compression and decompression functions binaries)
