non-strict hack :)
use Data::Dump qw/pp/;
@array = (10, 11, 12, 2, 3, 4, 7);
@a = sort {$a <=> $b} @array;
$first = $last = shift @a; # init start
push @a,"inf"; # infinity end
for $now (@a) {
unless ( $last+1 == $now ) {
push @ranges,[$first,$last]; # todo: one element ranges
$first=$now;
}
$last=$now;
}
pp @ranges;
not sure how you wanna handle one element ranges, so I kept it up to you:
([2, 4], [7, 7], [10, 12])

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.
