# An n-segment sequence

      _                 _
_  a |_  b |   c |   d     e   | f   | g |_  h     i     j/*End of Sequence*/
a |_  b   | c |   d |_  e |   f     g |_  h     i |   j/*End of Sequence*/


You find a piece of paper in the print tray with the above characters printed. You notice that the space between the h and the i is blank. What should be placed there and why?

Hint

P.S. I've used both and because I don't want to reveal what kind of a sequence it is. Will be valid here as well?
