Use the code below to say matched element count also, this will tell you the possible matches not only twice.
use strict;
use warnings;
use Data::Dumper;
my %hash_count;
my @array = ( "54321", "54312" , "5999" , "54352" , "12345"
+ );
my @original = ( "12345" , "54321" , "12355", "54321" );
foreach my $string(@array)
{
foreach my $string2(@original)
{
if ($string eq $string2) {
$hash_count{$string}++;
}
else
{
unless (exists $hash_count{$string})
{
$hash_count{$string} = 0;
}
}
}
}
print Dumper \%hash_count;
foreach (keys %hash_count)
{
unless ($hash_count{$_}) {
print "$_ Not found\n";
}
else
{
print "$_ found $hash_count{$_} times\n" ;
}
}
