( #3333=superdoc: print w/replies, xml ) Need Help??
that was too tough for me, so i asked a friend of mine (who is a real perl wizard but not very talkative). my own solution was hash-based too. he gave me this:
use strict; use warnings; print &compatible ("_8__3__19", "48____7__"); #c print &compatible ("_8__3__19", "4_8___7__"); #i print &compatible ("_8__3__19", "48_____7_"); #i sub compatible { my @s=($_[0], $_[1]); my @d; for( 0,1 ) { for( $d[$_]=$s[$_] ) { tr/0-9/\0/c; #assuming the placeholder is not \0 tr/\0/\377/c; } } my $m="$d[0]" & "$d[1]"; for( 0,1 ) { $d[$_] = "$m" & "$s[$_]"; } my $compatible; if( $compatible = $d[0] eq $d[1] ) { for( 0,1 ) { $d[$_] = {}; ${$d[$_]}{$1} .= "$-[0] " while $s[$_] =~ /(\d)/g; } $compatible &= !grep$d[1]->{$_} && $d[1]->{$_} ne $d[0]->{$_}, +keys %{$d[0]}; } return $compatible ? 1 : 0;; }
i canīt say i understand it fully but normally you can rely on ozo

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.
