1 原理哈夫曼编码(Huffman Coding),又称霍夫曼编码,是一种编码方式,哈夫曼编码是可变字长编码(VLC)的一种。Huffman于1952年提出一种编码方法,该方法完全依据字符出现概率来构造异字头的平均长度最短的码字,有…

Using the Huffman Coding technique, we can compress the string to a smaller size. Huffman coding first creates a tree using the frequencies of the character and then generates code for each character. Once the data is encoded, it has to be decoded. Decoding is done using the same tree. Hu...
