my %hash = map { $_, 1 } @array;
What is the usage of 1 in this code?
When you have any kind of doubt about a Perl structure, you can use
Data::Dumper:
use Data::Dumper;
my %hash = map { $_, 1 } @array;
print Dumper \%hash;
Try it!

What this does is creating a hash that looks like this:
%hash {
$array[0] => 1,
$array[1] => 1,
$array[2] => 1,
$array[3] => 1,
ect.
}
It is a (posibly the quickest way) of changing a array into a hash.
Hope it helps.
