HuffmanCodes
HuffmanCodes, commonly known as Huffman coding, is a widely used lossless data compression scheme developed by David A. Huffman in 1952. It assigns variable-length binary codes to symbols based on their frequencies in a source, producing shorter codes for more frequent symbols.
Construction: Given a set of symbols with probabilities, create a leaf node for each symbol. Repeatedly select
Optimality and limitations: For a fixed source distribution, Huffman coding produces an optimal prefix code that
Complexity and usage: Building the tree for n symbols takes O(n log n). Encoding and decoding use
