Challenge:
How many ways does Perl have to cut off the first char of a string?
conditions:
- no additional variables.
- no self-written subroutines
Here are the obvious solutions:
use strict;
my $s = "123456789";
substr($s,0,1)="";
print "$s\n";
$s =~ s/^.//;
print "$s\n";
$s = reverse $s;
chop $s;
$s = reverse $s;
print "$s\n";
I guess you can up with more?

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).
