(* stm, 6 June 2022: I did not edit the above code, but I believe that there is a small error. The Range@dictsize should be replaced by Range[0,dictsize-1] for LZW standard; Mathematica runs from 1 to 256 instead of 0 to 255. The code works as is in String format in Mathematica because Mathematica distinguishes between Strings and numbers. However, this example fails when the code is adapted to byte type input and output, as used in images. Adjusting Range[...] fixes the problem.*)
