Parts of the following may get you where you want to go:
use strict;
use warnings;
my $word = 'committee';
my @list = qw(t r e e);
my %remove;
$remove{$_}++ for @list;
for my $letter (keys %remove) {
--$remove{$letter} while $remove{$letter} and $word =~ s/$letter//
+;
}
#rebuild list
@list = ();
for my $letter (keys %remove) {
push @list, $letter while $remove{$letter}--;
}
print "Edited word: $word\nEdited list: @list";
Prints:
Edited word: commit
Edited list: r

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).

or How to display code and escape characters
are good places to start.
