How to create a Set of size N in Perl - Step by Step Examples

How to create a Set of size N in Perl ?

Answer

In 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.

✐ Examples

1 Create Set of Size N with Strings

In this example,

We create an array named @stringSet with initial string elements.
We ensure that the array contains unique elements to represent a set.
The number of elements in the array determines the size of the set.

Perl Program

use strict;
use warnings;

my @stringSet = ('apple', 'banana', 'cherry');
my $size = scalar @stringSet;

print "Size of stringSet: $size\n";

Output

Size of stringSet: N

2 Create Set of Size N with Integers

In this example,

We create an array named @intSet with initial integer elements.
We ensure that the array contains unique elements to represent a set.
The number of elements in the array determines the size of the set.

Perl Program

use strict;
use warnings;

my @intSet = (1, 2, 3);
my $size = scalar @intSet;

print "Size of intSet: $size\n";

Output

Size of intSet: N
