设计一个哈弗曼编译码器，功能如下:

(1)　　初始化：从终端读入字符集大小n，n个字符和n个权值，建立哈夫曼树，存入文件hfmTree

(2)　　编码：利用已建立好的哈夫曼树，对文件中的正文进行编码，存入文件CodeFile

(3)　　译码：利用已建立好的哈夫曼树将代码进行译码；或对目标正文编码，存入文件TextFile

(4)　　印代码文件：50个每行，存入文件CodePrin

(5)　　打印哈弗曼树:t同时将字符形式的哈弗曼树存入文件TreePrint

-Design a Hafu Man codec, the following functions: (1) Initialization: read from the terminal character set size n, n a n-weight character and to establish Huffman tree, into the file hfmTree (2) Coding: Using the Huffman tree has been well-established, the body of the document is encoded, stored in the file CodeFile (3) decoding: the use of already well-established code for decoding Huffman tree　or text encoding of the target , into the file TextFile (4) Indian code files: 50 per line, into the file CodePrin (5) Print Hafu Man Tree: t the same time, the character form of the tree into the file TreePrint Hafu Man
