Huffman compression is a lossless data compression algorithm that uses variable length encoding to represent each symbol in a message with a unique binary code based on its frequency.

The goal is to assign short codes to more common characters and long codes to less common characters to minimize the overall size of the compressed data. This algorithm is based on binary tree construction and is used in various applications such as image and audio compression, data transfer, and file storage.

Code length is proportional to the reciprocal of the symbol occurrence probability. The Huffman coding technique is an efficient technique for data compression because it keeps the length of the compressed data as short as possible.

Huffman compression, named after its inventor David A. Huffman, is a variable-length coding algorithm used for lossless data compression. In simpler terms, it's a way to represent data in a more efficient manner, reducing its size without losing any information.
