Since I don't see the glob trick mentioned in this thread, and I'm not too keen on your pick-random-combos-until-we-think-weve-got-them-all solution, here are two ways to solve the locker combo problem.

#!/usr/bin/perl -wT use strict; # golfed version using glob my $nums = join(',',1..31); my @list1 = glob("{$nums}-{$nums}-{$nums}"); print "L1: $_\n" for @list1; # more sane way of doing that..... my @list2; for my $i (1..31) { for my $j (1..31) { for my $k (1..31) { push(@list2,"$i-$j-$k"); } } } print "L2: $_\n" for @list2;
And here is the glob trick used to solve the original problem...
#!/usr/bin/perl -wT use strict; # one ordering.... my $letters = ',A,C,G,N,T'; my @list1 = grep {/./} glob("{$letters}"x4); print "L1: $_\n" for @list1; # different ordering my $letter2 = 'A,C,G,N,T'; my @list2 = (glob("{$letter2}"x2),glob("{$letter2}"x3),glob("{$letter2 +}"x4)); print "L2: $_\n" for @list2;
