Anonymous Monk Try this.
use strict;
use warnings;
use Tie::IxHash;
my (%hash1);
tie %hash1, "Tie::IxHash"; #To maintain the order
my @array = ("one", "two", "one", "three", "four", "one", "two");
$hash1{$_}++ for (@array);
my $hash = \%hash1;
print "$_ => $hash->{$_}\n" for ( keys %{$hash}); #Dereference and pri
+nt
outputs:
--------
one => 3
two => 2
three => 1
four => 1
I have used Tie::IxHash to maintain the insertion order, if order is not a matter, you can just ignore that. Also tak a look at hash and perlref.
