There are two different Lempel-Ziv algorithms LZ77 and LZ78. (You may use either one of these
in this lab.)
Your task is simple: Take a text file (which the machine represents as 0's and 1's) and compress
this file using the Lempel-Ziv algorithm.
As you performance metric, report the "compression ratio", defined in this context as the size of
the original file divided by the size of the compressed file.
