How do I remove white space in a Perl string?

Question

If I declared a variable $myString with the value \'3 \' (notice the white space). Is there any function to remove the white space for the return v

Answer 1

sub trim($)
{
    my $string = shift;
    $string =~ s/^\s+//;
    $string =~ s/\s+$//;
    return $string;
}


print trim($myString)
