一款Haffman编码！现代的压缩技术都是以它为基础！这些代码对文件的导入，算法，构建一棵树，遍历一棵树，最优解都有非常打得好处！能够很好的压缩txt文件！也能解码！是原来的四分之一大小到七分之一大小。真的很不错！-A Haffman coding! Of modern compression technologies are based on it! These codes into the document, the algorithm to construct a tree, traverse a tree, the optimal solution has a very good play! Txt files can be compressed very good! Can also be decoded! Is the original size of up to seven times the size of a quarter. Really nice!
