LZ77 and LZ78 are dictionary-based compression
LZ77 and LZ78 are compression algorithms that work by storing repeated data as references instead of rewriting it. This dictionary-based approach greatly reduces file size by pointing back to earlier parts of the data. It forms the foundation of popular formats like ZIP archives, PNG images, and GIF files. The method is efficient because it ...
