Don't shadow built-ins. Especially for a function name.

here are the answers:
Perl code:
sub reduce ($$) {
my %hh= %{$_[0]}; # e.g. {'1,2'=>[1,2],'5,6'=>[5,6],...}
my ($j1,$j2)=($_[1]->[0],$_[1]->[1]); # e.g. [3,4]
delete $hh{"$j1,$j2"};
foreach my $k (keys %hh) {
$k=~m/^(\d+),(\d+)$/;
my ($k1,$k2)=($1,$2);
if ($k1==$j1) {

attached below is the Perl documentation that i wrote for a function
called "reduce", which is really the heart of a larger software.
The implementation is really simple, but the key is to understand what
the function should be. I'll post
