  Question 77 :
      Write a program to compress and decompress the string
      "hello world!hello world!hello world!hello world!"
  
      Hints : Use zlib.compress() ans zilb.decompress() to
      compress and decompress a string.

  # Solution :
  
  import zlib

  zlib.compress(s) in python :
      With the help of zlib.compress(s) method, we can get compress the
      bytes of string by using zlib.compress(s) method
  
  zlib.decompress(s) in python : 
      We can decompress the compressed bytes of string into original
      string by using : zlib.decompress(s) method
