- First , the program will scan compressed files and save input character in file , ( nhapDuLieu function ( ) ) and then sorted in order of the appearance of the regular characters .- Next, used to encrypt data to create Huffman tree by taoCayHuffman method ( ) . Data will be stored in the output file . Later when decoding uses the stored data to generate the Huffman tree used for the decompression .- Use ListNode is a double link list HuffmanNode store . Each HuffmanNode 7 components , including the cursor left, right .+ Symbol is character .+ Freq is the number of characters matched .+ Codeword is the decimal representation for the corresponding binary number . For example codeword of A is 3 , which corresponds to the binary code 011 .+ CodewordLen stored bits in codeword number to avoid confusion with 0011 or 11 011 or 00011 ...+ RunLen length of characters identical- Principle of operation of the encode ( ) : for example, in the original input file containing the string AAAB , AAA
