+LZ77 is a family of lossless [Data Compression](/wiki/data_compression) algorithms, foundational to modern schemes. It works by finding repeated sequences within the input data and replacing them with short references to their previous occurrences. This elegant approach forms the basis for widely used formats like [Deflate](/wiki/deflate).
