A Huffman code generator is a tool that implements the Huffman coding algorithm, a powerful lossless data compression technique. It utilizes statistical analysis to create variable-length codes for symbols, with more frequent symbols assigned shorter codes. By constructing a binary tree based on symbol probabilities, the generator allocates optimal bit sequences to each symbol. The generated Huffman codes minimize data redundancy, reducing file sizes without loss of information. This code generation process involves maintaining a priority queue to organize symbols and constructing a symbol table to map symbols to their corresponding binary codes. Huffman coding finds wide application in image compression (e.g., JPEG), text compression, and other data transmission scenarios where file size reduction is crucial.
