这是一个简单的LZW编码程序，能实现字典编码的基本工能！用码树实现！实现LZW编码和译码，任意数一段字符之后，就能实现对其的LZW编码，按照格式输入一段解码字符段，会解码出字符！-This is a simple LZW coding procedure, can realize the basic encoding dictionary work can!!!! Tree with code true! Realize the coding and decoding LZW, arbitrary number after a character, can achieve its LZW code, according to the format input a decoding character section, a character can decode!
