Hi,
I have a set of 8 1D arrays each containing around 100 to 150 ids. I want to recursive
parse each array to find what is common and unique across all 8 arrays and print that
out. Does any one know of an algorithm or has an idea that recursively could do the
task?
Thanks in advance for your
It's not recursive, but it should do the job...
my %ids = ();
foreach (@arr1) { $ids{$_}++;}
...
foreach (@arr8) { $ids{$_}++;}
foreach (keys(%ids)) { print $_ if $ids{$_} == 8; }
This assumes that each array contains only unique ids.

In general, when you have basic algorithmic task such as below, I recommend
first using http://search.cpan.org to find out if someone has packaged the
functionality you need as a module. Usually you find such a module. And in
fact, I found List::Compare, which seems to do exactly what you have
