'''
You've surely seen a seven-segment display.

Your task is to write a program which is able to simulate the work of a seven-segment display device, although you're going to use single LEDs instead of segments.

Each digit is constructed from 13 LEDs (some lit, some dark, of course) - that's how we imagine it:

  #  ###  ###  # #  ###  ###  ###  ###  ###  ###
  #    #    #  # #  #    #      #  # #  # #  # # 
  #  ###  ###  ###  ###  ###    #  ###  ###  # # 
  #  #      #    #    #  # #    #  # #    #  # # 
  #  ###  ###    #  ###  ###    #  ###  ###  ###

Note: the number 8 shows all the LED lights on.

Your code has to display any non-negative integer number entered by the user.

Tip: using a list containing patterns of all ten digits may be very helpfull
