that min functions looks kinda funny, and in some ways manages to expose the dangers of writing lazy (ie, terse) perl.
sub min {
my $min = shift;
foreach (@_) {
$_ = $min if $_ < $min;
}
return $min;
}
@a = (10, 5, 8, 2, 1, -4);
$min = min(@a);
print "min of @a is $min\n";
produces: min of 10 10 10 10 10 10 is 10
probably not what you expected! not only did it give the wrong answer, it destroyed the input list!

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).
