Create a class RLE that employs fixed-length encoding and very few distinct characters to compress ASCII bytestreams, incorporating the code as a component of the encoded bitstream. Add code to compress() to create an Alphabet using all the message's different characters, prepend alpha (8-bit encoding plus its length) to the compressed bitstream, and then add code to expand() to read the alphabet before expansion.
