How to create a Set of integers in Perl ?

Answer

To create a set of integers in Perl, you can use a hash or an array to store unique integers.

✐ Examples

1 Create a Set of Integers using Hash

In this example,

We create a hash named %intSet to store unique integers as keys.
We use the keys of the hash to represent the set of integers.

Perl Program

%intSet = (1 => 1, 2 => 1, 3 => 1, 4 => 1, 5 => 1);
print "Set of integers: ", join(', ', keys %intSet), "\n";

Output

Set of integers: 1, 2, 3, 4, 5

2 Create a Set of Integers using Array

In this example,

We create an array named @intSet to store unique integers.
We use the elements of the array to represent the set of integers.

Perl Program

@intSet = (1, 2, 3, 4, 5);
print "Set of integers: @intSet\n";

Output

Set of integers: 1 2 3 4 5
