Another version:

use strict; use warnings; my $grid = join('', <DATA>); $grid =~ s/\n//g; my $n = sqrt(length $grid); my @sqs; while( $grid =~ /(.*?)[.x]/ ) { my $sq = ('A'..'Z')[scalar(@sqs)%26]; my $pos = length $1; substr( $grid, $pos, 1 ) = '.'; my $i = 1; my $x = $pos%$n; my $y = int $pos/$n; $i++ while $x+$i < $n and $y+$i < $n and join( '', map { substr($gri +d,$_*$n+$x,$i+1) } $y..$y+$i ) eq '.' x (($i+1)*($i+1)); substr($grid,$_*$n+$x,$i) = $sq x $i for $y..$y+$i-1; push @sqs, [ $x+1, $y+1, $i, $sq ]; $sq++; } print substr($grid,$n*$_,$n)."\n" for 0..$n-1; print "@$_\n" for @sqs; __DATA__ ............ .........x.. ......x..... ..x......... x........... ....x....... .......xx... ..x......... ..x.....x... ..x......... .x.....x.... ............

Title:
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.
