Concatenation in Perl

Hi ,

I am doing a concat operation in Perl  for a string like below : -

if( @folders ) {

    map {$query .= "not in:$_ and"; } @folders;
    print "\n $query \n";

    }

@folders contain - Inbox, Sent

Output from above is - *not in:Inbox and not in:Sent and*
Expected is = *not in:Inbox and not in:Sent* ----> ie without extra and
after Sent

I tried this with join as well as :-

my $query="";
foreach my $folder ( @folders )
{
$query = join "and" "not in:$folder" "$query";
}

but still same result and this time extra "and" in beginning.

 Any idea how to do this ?


Best Regards.
