一个哈夫曼算法.具体题目如下: 题目要求：1）建立一正文文件(本程序中建立的文件名文test.txt)，向其中输入字符（本程序中可输入任意ASCII值） 2）通过哈夫曼算法求出文件中字符的相应编码 3）建立一与正文文件(test.txt)对应的编码文件（本程序中为bainma.txt）-a Huffman algorithm. Specific topics are as follows : Subject : 1) the establishment of a text document (the procedures established in the File Name text test.txt), which imported to the character (this program can import arbitrary ASCII values) 2) by Huffman algorithm obtained documents characters The corresponding coding 3) and the establishment of a text document (test.txt) corresponding encoded files (the procedures for bainma.txt)
