zip压缩，解压缩代码.

文件压缩功能：压缩指定单个文件，或多个文件（zip格式）；察看压缩文件内每个文件的大小，压缩比信息；解压缩指定文件（zip格式），允许选择压缩包内单个文件进行解压缩；察看整个压缩包的压缩比等信息。-compression function : Compression designated single document, or multiple documents (zip format); A look inside compressed files, each file size, compression ratio; Decompress the specified file (zip format), allowing choice within a single compressed file decompression; Look at the whole compression packet compression ratio and other information.

) Compression using huffman code -with a number of bits k per code word -provide huffman table Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree. -) Compression using huffman code -with a number of bits k per code word -provide huffman table Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol.
