传统哈夫曼编码借助树形结构构造，算法实现时使用链表或静态链表结构，空间的每个结点内有左、右子树、双亲指针。

Traditional Huffman coding is structured in the way of tree pattern, using the chain or static chain structure in algorithm, and every node in space has left, right tree and parents Pointers.

而且每棵哈夫曼树都必须有以下结构：编码，信息，频度，双亲，左孩子，右孩子。

Secondly every Huffman tree must have following structure code, data, weight, parent, l-child and r-child but only code and data are needed in decoding .
