Thus using Huffman encoding technique , we can achieve a lossless data compression of nearly 80% . In the above example, the 11 bytes input data is compressed into just 3 bytes. #ifndef HUFFMAN_H #define HUFFMAN_H /* Header files */ #include /* Return values */ #define EXIT_SUCCESS 0 #define MEM_ERROR 1 #define INPUT_ERROR 2 /* Node identifiers, might change to enumeration */ #define INTERNAL_NODE 0 #define BYTE_NODE 1 #define HEADER_BASE_SIZE 10 /* Size of the header with no bytes stored */ #define MAX_CODE_LEN 16 /* The longest any encoded representation huffman coding a data compression technique which varies the length of the encoded symbol in proportion to its information content, that is the more often a symbol or token is used, the shorter the binary string used to represent it in the compressed stream. huffman codes can be properly decoded because they obey the prefix property, which means that no code can be a prefix of another code I'm looking for code review, optimizations, best practices. /** * Huffman encoding obeys the huffman algorithm. * It compresses the input sentence and serializes the "huffman code" * and the "tree" used to generate the huffman code * Both the serialized files are intended to be sent to client.

There is more than one valid Huffman code possible with that set of probabilities. If you take the sum of the probabilities times the bit lengths for both Huffman codes, you will find that those sums are exactly the same. Huffman Codes (i) Data can be encoded efficiently using Huffman Codes. (ii) It is a widely used and beneficial technique for compressing data. (iii) Huffman's greedy algorithm uses a table of the frequencies of occurrences of each character to build up an optimal way of representing each character as a binary string. Huffman’s algorithm for computing minimum-redundancy prefix-free codes has almost legendary status in the computing disciplines.

In this algorithm, a variable-length code is assigned to input different characters. The code length is related to how frequently characters are used. Most frequent characters have the smallest codes and longer codes for least frequent characters.

we have to compare the representation . Huffman code is a way to encode information using variable-length strings to represent symbols depending on how frequently they appear. The idea is that symbols that are used more frequently should be shorter while symbols that appear more rarely can be longer.
