[Solved] Generateing all possible 16 digit number requireling less storage location


If I understand you correctly then all that code is just to avoid printing numbers that have more than eight zeroes

You can do that like this

my $credit_card_number = "$a$b$c$d$e$Fc$g$h$i$j$k$l$m$n$o$p";
print $credit_card_number, "\n" unless $credit_card_number =~ tr/0// > 8;

But I still think your enterprise is a fruitless one
