  • Huffman
    说明:  数据结构:Huffman编码。哈夫曼编码是哈夫曼树的一个应用。哈夫曼编码应用广泛,如JPEG中就应用了哈夫曼编码。 哈夫曼树又称最优二叉树,是一种带权路径长度最短的二叉树。(Data structure: Huffman coding. Huffman coding is an application of the Huffman tree. Huffman coding is widely used, such as JPEG in the application of the Huffman coding. Huffman tree, also known as the best binary tree is a weighted shortest path length binary tree.)
