ProgramGuruIn Perl, sets can be represented using arrays or the Set::Scalar module. To create a set of size N with different types of items using arrays, you can use arrays with unique elements.
In this example,
@stringSet with initial string elements.use strict;
use warnings;
my @stringSet = ('apple', 'banana', 'cherry');
my $size = scalar @stringSet;
print "Size of stringSet: $size\n";Size of stringSet: N
In this example,
@intSet with initial integer elements.use strict;
use warnings;
my @intSet = (1, 2, 3);
my $size = scalar @intSet;
print "Size of intSet: $size\n";Size of intSet: N
In this tutorial, we learned How to create a Set of size N in Perl language with well detailed examples.
