这是一个霍夫曼编码的程序，是利用霍夫曼树等相关算法解决的。在程序中，随机产生的10个字符，利用子函数：

HC=HuffmanCoding(HT,HC,w,3) 则可以获得每个元素的码字，存储的方式是通过一个指针的指针。-This is a Huffman coding process is the use of Huffman tree related algorithms to solve. In the process, the randomly generated 10 characters, using Functions: HC = HuffmanCoding (HT, HC, w, 3)　are available for each element of the code words, storage is through a pointer.
