建立一个文本文件A，统计该文件中各字符的频率，对各字符进行Huffman编码，将该文件翻译成Huffman编码文件B，再将Huffman编码文件译码成文件C，并对文件A与C进行比较。 要求：能够对dat、txt等类型文件进行压缩 -The establishment of a text file A, statistics that document the frequency of the characters, the characters of Huffman coding, th

设一段电文中有不同出现频率的字符，为了提高电文的输入和翻译效率，必须有一套简短而又不会产生歧义的字符代码。试根据哈夫曼算法，对电文中的不同字符，构造出一棵哈夫曼树，对每个字符进行编码。-Set a message in the frequency of different characters, in order to enhance the message of the input and translation efficiency, we must have a brief charact

程序实现如下功能：输入一段长度不超过100的字符串，将其进行霍夫曼编码并输出。将编好的霍夫曼码再次输入，输出解码后的字符串。-The program to achieve the following functions: enter a period does not exceed the length of the string of 100, Huffman encoded and output. The programmed the Huffman code again input, ou

建立哈夫曼函数，编码，翻译编码，分别用统计函数和排序函数来实现统计和排序的功能-To establish the the Huffman function, encoded, translated coding, statistical functions and sorting function statistics and sort functions
