[Crack Hack] ztrees DL : 0: *讨论 * 本PKZIP“通缩”的过程中使用了几个哈夫曼树。越 *共源的值由短比特序列表示。 * *每个代码树存储在ZIP文件以压缩形式 *这是本身的长度的霍夫曼编码 *所有的代码串（按升序排列按来源值）。 *实际代码串从长度重构 *解压缩过程中，如在“应用指南”中描述 *（APPNOTE.TXT）分布情况的PKWARE的PKZIP的计划的一部分。-* trees.c by Jean-loup Gailly * * This is a new version of im_ctree.c originally written by Richard B. Wales * for the defunct implosion method. * * PURPOSE * * Encode various sets of source values using variable-length * binary code trees. * * DISCUSSION * * The PKZIP deflation process uses several Huffman trees. The more * common source values are represented by shorter bit sequences. * * Each code tree is stored in the ZIP file in a compressed form * which is itself a Huffman encoding of the lengths of * all the code strings (in ascending order by source values). * The actual code strings are reconstructed the lengths in * the UNZIP process, as described in the application note * (APPNOTE.TXT) distributed as part of PKWARE s PKZIP program.
