    I have to implement 3 data compression algorithms. I was thinking about LZW, Deflate and Bzip2. I can't find any good documentation for these algorithms. Do you know any data compression algorithms with good documentation, samples etc.?

      I find that extremely hard to believe. A TON of documentation and discussion comes up with a simple Google for "LZW compression algorithm" "Deflate compression algorithm" and "bzip2 compression algorithm". If you were looking for copy'n'paste code, yeah, that's going to get you a failing grade in class.

        Yes, but your claims are just impossible, so you will have to search again. Don't fool us, April fools was 1 week ago.

            Run-length encoding is a very simple one. It will save you some work by substituting it for one of the complex ones you mentioned.

              You can implement following algorithms very easily:
              RLE
              Huffman
              Rice
