A pattern? Yes, of course!
Here what you can obtain if you paint a Pascal Triangle.

Update I think this link could be amusing: Pascal's Triangle

#!/usr/bin/perl use strict; my $n = 10; for my $i (0 .. $n) { for my $j (0 .. $i) { my $coefficient = nCr($i, $j); if ($coefficient % 2) { print '#'; } else { print ' '; } } print "\n"; } # returns n!/r!(n-r)! sub nCr { my $n=shift; my $r=shift; return int nFactorial($n) / int nFactorial($r) * int nFactorial($n +-$r); } # like the name says, n! sub nFactorial { my $n=shift; my $product = 1; while($n>0) { $product *= $n--; } return $product; }

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
