This repository contains working implementations of two classic data compression algorithms, written in the C programming language. Lempel-Ziv algorithms are methods for squeezing data down to a smaller size, the kind of compression you might see in ZIP files or image formats. Instead of storing raw data, these algorithms spot patterns and repetition, then replace them with shorter codes. The two variants here are LZW (Lempel-Ziv-Welch) and LZ77, which use slightly different strategies to find and encode those patterns. LZW builds a dictionary of patterns as it reads the data, while LZ77 looks back at data it's already processed to find matching chunks. The README doesn't elaborate on the specific features or implementation details, so it's unclear whether this repo includes both compression and decompression, example files to compress, or documentation of the algorithms themselves. For someone learning about compression, this would be a place to see how these foundational algorithms actually work in code. For a developer needing compression functionality, this could serve as a reference or starting point, though you'd want to check whether the implementations are optimized for production use or mainly educational. If you're interested in how data compression works under the hood, or you're building something that needs to shrink file sizes and want to understand these classic techniques, this repo gives you a direct look at the algorithms in action.
