In Perl, you can use a hash to create a collection of unique strings.
In this example,
%stringSet
to store strings.1
.# Create a hash of strings
my %stringSet;
# Add strings to the hash
$stringSet{'Apple'} = 1;
$stringSet{'Banana'} = 1;
$stringSet{'Cherry'} = 1;
# Print the hash
use Data::Dumper;
print Dumper(\%stringSet);
$VAR1 = { 'Banana' => 1, 'Apple' => 1, 'Cherry' => 1 };
In this example,
# Check if the hash contains a key
my $containsBanana = exists $stringSet{'Banana'};
print "Hash contains Banana: $containsBanana\n";
