Description: Huffman coding is optimal variable-length code, the design of a Huffma coding process, realize the following functions: (1) to receive the raw data: Reading from the terminal into the character set size n, and n characters, and the right values, the establishment of Huffman tree, and It documents in hfmtree.dat. (2) Coding: Using the Huffman tree has been established to document the body encode the results into a document in codefile.dat. (3) Decoding: The number has been established Huffman tree will sodefile.dat decoding of code, resulting in a document deposited in textfile.dat. (4) Print coding rules: that is, characters with one-to-one relationship between the encoding. (5) Print Huffman tree will have been deposited in the Huffman tree in memory intuitive way to show that in the terminal.
