HI monks. I have question about checking combination of sum. I want to check that array can generate pairs of sum. Please give me nice algorithm.. I could't make script.. 
my @input = qw/ 2 5 7 /;
my $target = 15;

my @want_output = (
(5 5 5)
(2 2 2 2 7)
....
)
my $target2 = 3
my @want_output = fail;
