) Compression using huffman code -with a number of bits k per code word -provide huffman table Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree. -) Compression using huffman code -with a number of bits k per code word -provide huffman table Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol.

Structure the sources so that the compression and decompression code form a library usable by any program, and write both gzip and zip on top of this library. This would ideally be a reentrant (thread safe) library, but this would degrade performance. In the meantime, you can look at the sample program zread.c.-Structure the sources so that the compress ion and decompression code form a library usabl e by any program, and write both gzip and zip on top of this library .
