    Don't worry about the whole problem, just work on smaller parts and build upon. Can you write code to produce:
      X
     XXX
    XXXXX
    If so then you are half way there. All you need to do after that is to repeat the pattern but upside down. Depending upon how you wrote the program you might end up with 2 middle lines. If so then work out how to eliminate one.

    Start with a piece of paper (graph paper would work well). Write down the all the X's for 3 or 4 lines. Then count how many X's and how many spaces are on each line. Do you see a pattern?
