In Perl, sets are not a built-in data structure. However, you can achieve similar functionality using arrays. To sort the items of a 'set', you can convert the array to a list and then sort the list.
In this example,
@numbers
containing some integer elements.sort()
function.my @numbers = (5, 3, 1, 4, 2);
@numbers = sort {$a <=> $b} @numbers;
print "Sorted numbers:\n";
foreach my $number (@numbers) {
print "$number\n";
}
Sorted numbers: 1 2 3 4 5
In this example,
@fruits
containing some string elements.sort()
function.my @fruits = ('Banana', 'Apple', 'Cherry', 'Date');
@fruits = sort @fruits;
print "Sorted fruits:\n";
foreach my $fruit (@fruits) {
print "$fruit\n";
}
Sorted fruits: Apple Banana Cherry Date
