Ajusted to only do it once:
my $first = 1;
@array = map {
if ($first && $_ eq "c") {
$first = 0;
($_, "x")
} else {
$_
}
} @array;
hum, ugly. How about:
my $first = 1;
@array = map {
my @a = $_;
push(@a, "x") if ($first && $_ eq "c");
$first ||= @a-1;
@a
} @array
Nope, still ugly. Well, you could always do:
foreach (0..$#array) {
if ($array[$_] eq "c") {
splice(@array, $_+1, 0, "x");
last;
}
}

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.
