数据的最优编码(optimal code)方案总是对应着一棵满二叉树(full binary tree). 可以采用反证法证明: 若某个最优编码不是满二叉树, 则存在某个内部结点, 有空的左子树或右子树, 此时, 如果将这个内部结点的编码直接设置为非空的右子树或左子树的编码, 这样会使经过这个内部结点的所有字符码字长度少1, 可获得...

Output the codeword for each input symbol. The first and the last subproblems are easy. For the first subproblem we only need a data structure to allow the access to each symbol one after another. Suppose the prefix code is C = (c1, c2,…, cn), where n =8 in this example. For ...

This technique produces a code in such a manner that no codeword is a prefix of some other code word. These codes are called as prefix code.Algorithm for Huffman code1. Input:-Number of message with frequency count. 2. Output: - Huffman merge tree. 3. Begin 4. Let Q be the priority...
