[SPOILER]match of the week solution

Not entierly to spec :-) but here's a fairly short RR alocation routine  
using a circle methaphor.

    a      a      a
   d b -> c d -> b c
    c      b      d

place all the teams around a circle, keep the one at 12 oclock fixed and  
rotate the rest. Pair off oposing teams.
(you obiously need an even number of teams so / ("no team") is added if  
odd number)


#!/local/bin/perl5 -w
use strict;

my @teams = qw(A B C D E F);
my @list;

push @teams, '/' if @teams % 2;
for my $round (0 .. @teams-2) {
    push @teams, splice @teams, 1, 1;
    @{$list[$round]} = map "$teams[$_]-$teams[@teams-$_-1]", (0 .. @teams  
/ 2 - 1);
}
for (@list){print "@$_\n"};
