How to get Subset from a Set in Perl ?

Answer

To get a sub Set in Perl, you can use array slicing.

✐ Examples

1 Get Sub Set with Items

In this example,

We define an array named @mySet containing elements of a specific type.
We specify the range of indices to extract the sub Set.
We use array slicing with the specified range to get the sub Set.

Perl Program

# Define array with items
my @mySet = ("apple", "banana", "orange", "grape", "melon");

# Get sub Set with items
my @subSet = @mySet[1..3];
print "Sub Set with items: @subSet\n";

Output

Sub Set with items: banana orange grape

2 Get Sub Set from Empty Set

In this example,

We define an empty array named @mySet.
We attempt to get a sub Set from the empty array, which results in an empty sub Set.

Perl Program

# Define empty array
my @mySet = ();

# Get sub Set from empty array
my @subSet = @mySet[1..3];
print "Sub Set from empty array: @subSet\n";

Output

Sub Set from empty array:
