The algorithm uses a fixed set of complementary parity codes to replace the encodingtable that dynamically generated by the traditional Huffman method.
该算法使用固定奇偶码,省去了传统算法动态生成哈夫曼树的繁琐过程;

The history table must not include a period and must have the same encoding scheme and Coded Character Set Identifier (CCSID) as the temporal table (see Listing 2).
