suanshu
- 首先，计算出码元符号集中各个码元的累积概率，并存放在F数组里面。 然后，开始循环编码，直至输入序列循环完毕。 最后，将所得的累计概率由小数形式转化成二进制形式。 对解码。首先，计算码元符号集中各个码元的累积概率，并存放在F数组里面。 然后，开始循环解码，此次循环是在码元符号集中，由高概率码元向低概率码元循环，这是由于编码的输出肯定是不大于高概率码元的累积概率的。那么如果我们从高到底循环，所找到的第一个小于编码结果fs的码元即为所译码的码元。 最后，我们可以利用此码

hfmcpp
- 赫夫曼编码本程序实现了使用赫夫曼编码压缩数据；输入一串字符串sourceCode——为方便理解，暂时要求字符串只包含大写字母和空格，如果你愿意， 很容易就可以推广到所有的字符——计算出字符串中各个字母的权重，然后对其进行赫夫曼编码，输出赫夫曼树。 将赫夫曼树的叶子结点存储到有序二叉树中，输出原字符串经压缩后得到的用 0 和 1 表示的新字符串destCode； 然后利用赫夫曼树将字符串destCode进行译码，得到目标字符串objCode，比较objCode和sourceCod
