n = 3 (broken into lines as nonoob suggested)

0         __

1      __/  \__

2   __/  \__/  \__

3  /  \__/  \__/  \

4  \__/  \__/  \__/

5     \__/  \__/

6        \__/

Let n be the input number and i be the current line (as numbered above).

Line 0 is always
        __

Lines 1 to n - 1 all begin and end like this

    __/    \__

Line n begins and ends like this

   /          \

Lines 2 to n have i - 1 of these in the middle

     \__/

Lines n+1 to 2n are made up of 2n - i + 1 of these

     \__/

The rest is all spacing, the trickiest part.

here is my scrip, i can complete the middle part. this (\_/) part. can anyone help me???

It may look it, but actually it isnt (BTW - excellent analysis, you'd get an 'A' from me; I wish more newbies showed the same application).

If you look at your patterns closely, you'll see that they repeat. If I was doing it, I wouldn't worry too much about spaces on the right (so, you print extra spaces on a line; who cares?) it may help you to see how to put your "shapes" together.

For me, there are 6 basic shapes:
1. Hex top (see line 0).
2. Left top and right top (line 1, but two distinct shapes that may need to be used separately).
3. Left edge and right edge (line 3, but again, two distinct shapes that may need to be used separately; and needed only once, from the looks of it).
4. A "cup" (the teacup without a handle, used everywhere else).
The rest is all leading spaces.

See if that helps any.

Good luck.

Winston

[Edit] Looking at it again, there are other ways of looking at the pattern, but I'd get what you have working first, then look for alternatives.
