这是一个练习使用位写入/写出的程序，利用bitio.c和bitio.h工具整合，可以向文本文件E:\bitio1.txt中读取和写入数个位，使用者可以通过调试功能进一步了解位写入写出的作用。进而给今后做数据压缩打下基础。(This is a practice using bit write/write program, using bitio.c and bitio.h tool integration, you can read and write several bits to the text file E: \ bitio1.txt, the user can pass Debugging function to further understand the role of bit write write. And then lay the foundation for future data compression.)

This function quickly finds local peaks or valleys (local extrema) in a noisy vector using a user defined magnitude threshold to determine if each peak is significantly larger (or smaller) than the data around it. The problem with the strictly derivative based peak finding algorithms is that if the signal is noisy many spurious peaks are found.

实现Huffman算法，对数据进行最优编码压缩。(huffman code)

动态规划中图形算法中的最短路径算法 用类做的，分几个函数(The short road of dymta i don t know what is this program means，it is a c++ program ！numeric recipes in C++ )

压缩与解压缩类；压缩文件至.zip包内，增加文件至.zip包内，及解压缩相关操作。(zip and unzip。)

利用Huffman编码方式对一段文字进行编码和解码。哈夫曼编码是可变字长编码(VLC)的一种。(Using the Huffman encoding method for encoding and decoding of a paragraph of text. Huffman code is a variable length coding (VLC) is a kind of.)
