Good Morning! I searched around and I didn't find much on it. I have 2 array references and I am searching one for combinations of keys that match the other one. The inner one is the small one. When I find one, I would like to remove it from the inner array to reduce the total search space on the next iteration. My example shows the algorithm, but I didn't post the loading of the arefs. Any recommendations on a different algorithm? Any recommendations on how to modify that array? I saw in the Perl Docs that delete will be deprecated.

any suggestions would be good.

thanks -theleftsock

use warnings; use strict; my ($outer_hr_aref, $inner_hr_aref); foreach my $outer_href (@$outer_hr_aref) { foreach my $inner_href (@$inner_hr_aref) { if (($$outer_href{key1} eq $$inner_href{key2}) & ($$outer_href +{key3} == $$inner_href{key4})) { #abitrary key assignment could be ot +her combinations print "status found: $$inner_href matching $outer_href\n"; $$outer_href{key1} = 'something_new'; #arbitrary, other fu +nction calls can occur #somehow now remove the $inner_href item from the @$inner_ +hr_aref so i don't have to search the entire aref again. last; } } }
