Huffman coding requires that both the encoder and decoder have the same table of codewords. In some systems (e.g., JPEG) this table is transmitted prior to the data (see Fig. 7.7). The procedure for creating a basic Huffman tree is as described by Algorithm 7.1. It should be clear ...

Your solution will use the Huffman coding algorithm to both compress and decompress files. For compression it will create the encoded version of the input file by using the ASCII characters for 0 and 1. This means your compressed output will actually be larger than the original. The idea here...
Huffman coding A statistical compression method that converts characters into variable length bit strings. Most-frequently occurring characters are converted to shortest bit strings; least frequent, the longest. Compression takes two passes. The first pass analyzes a block of data and creates a tree ...
