quazip 采用qt 进行解压和压缩,本源码来源官网，可以生成a文件和dll 文件，使用时将a文件和dll文件加入工程中，另外要将头文件加入到工程之中。经本人测试可用

huffman 编码 完陈对指定的文本文件内容进行huffman编码 实现输出(END CHAN huffman encoding text file on the specified content encoding huffman implementation output)

文件的解压缩。添加文件unzip.h、unzip.cpp、zip.h、zip.cpp，调用对应函数进行压缩和解压。压缩格式为zip；压缩之后的文件可以用winrar等程序打开。(File decompression. Add file unzip.h, unzip.cpp, zip.h, zip.cpp, call the corresponding function for compression and decompression. Compression format is zip the file after compression can be opened by winrar.)

Codes". Huffman coding uses a specific method for choosing the representation for each symbol, resulting in a prefix code (sometimes called "prefix-free codes") (that is, the bit string representing some particular symbol is never a prefix of the bit string representing any other symbol) that expresses the most common characters using shorter strings of bits than are used for less common source symbols. Huffman was able to design the most efficient compression method of this type: no other mapping of individual source symbols to unique strings of bits will produce a smaller average output size when the actual symbol frequencies agree with those used to create the code. A method was later found to do this in linear time if input probabilities (also known as weights) are sorted.

网规网优之用，用于绘制基站扇区图，地理化显示基站方便工程师进行查看。(Net regulatory network optimization purposes, used to map the base station sector maps, geographic-based display base stations to facilitate engineers to view it.)

说明：  一个简单的32位位图压缩算法，基本思想是，扫描像素点，后面有雷同的就记下重复次数。(A simple 32-bit bitmap compression algorithm, the basic idea is to scan pixel, behind identical repetitions on the record.)

ssr科学上网工具，该压缩文件已经配置好了，直接解压就可以使用了。(SSR scientific Internet access tool, the compressed file has been configured, the direct decompression can be used.)

matlab实现的huff图像压缩程序 可成功运行((matlab implementation of huff image compression program which can be run successfully))

代码实现了基于ARM7的MPEG-4视频解码器，由C代码和汇编混合编写，已经在ARM7TDMI平台调试通过。(Code based on the ARM7 realize the MPEG-4 video decoder, from C code and compilation of mixed-prepared, has been adopted ARM7TDMI debugging platform.)

说明：  脑筋急转弯，有答案提示，支持修改问题，添加脑筋急转弯！(Riddles, answer prompts, to support amending add Riddles!)
