Huffman encoding and decoding demo 1, from the initial information given in the interface to select the appropriate function 2, read from the terminal character set size n, and n and n characters of the right values. Huffman tree establishment, and it is stored in documents hfmtree.dat in 3, has been built using huffman trees tobetran.dat the document is encoded in the body, and then the results into a document in codefile.dat 4, has been built using huffman tree will be a good document codefile.dat decoding of the code, the result into the document in textfile.dat 5, in order to compact the file format codefile.dat displayed on the terminal, 50 per line 6, will have huffman tree in memory intuitive way to show that in the terminal
