# LZW Compressing tool
This is a university assignment for which I aim to create an LZW algorithm implementation to create a small tool similar to `gzip` and `gunzip` that can compress and uncompress files in a lossless fashion.
This project is written is C++17, compiled with clang under a UNIX environment. Other compilers and environments will not be tested.
