huffman encoding
In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression. The process of finding and/or using such a code proceeds by means of Huffman coding, an algorithm d, 前言: 在考慮檔案壓縮時, 每個字元都必須有一個二元編碼, 而 Huffman Code 則是最節省空間的字元編碼方式. 建立Huffman Tree : 考慮以下字串: a a a b b c d d d d d d e e e e e f f g g g g g g h h h h i i i. (一) 針對相異字元, 統計其出現的個數: (二) 為每個字元建立一顆單一節點的樹, 每棵樹的根節點之關鍵值(紅色字) ...

霍夫曼編碼 - 维基百科
霍夫曼編碼（英语：Huffman Coding），又譯為哈夫曼编码、赫夫曼编码，是一種用於無損數據壓縮的熵編碼（權編碼）演算法。由大衛·霍夫曼在1952年發明。 在计算机資料處理中，霍夫曼編碼使用變長編碼表對源符號（如文件中的一個字母）進行編碼，其中變長編碼表是通過一種評估來源符號出現機率的方法得到的，出現機率高的字母 ... https://zh.wikipedia.org Huffman coding - Wikipedia
