How to Sort Items of a Set in Perl - Step by Step Examples

How to Sort Items of a Set in Perl ?

Answer

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.

✐ Examples

1 Sort Items of an Integer 'Set'

In this example,

We create an array named @numbers containing some integer elements.
We sort the array using the sort() function.
Finally, we print the sorted array to the console.

Perl Program

my @numbers = (5, 3, 1, 4, 2);
@numbers = sort {$a <=> $b} @numbers;
print "Sorted numbers:\n";
foreach my $number (@numbers) {
    print "$number\n";
}

Output

Sorted numbers:
1
2
3
4
5

2 Sort Items of a String 'Set'

In this example,

We create an array named @fruits containing some string elements.
We sort the array using the sort() function.
Finally, we print the sorted array to the console.

Perl Program

my @fruits = ('Banana', 'Apple', 'Cherry', 'Date');
@fruits = sort @fruits;
print "Sorted fruits:\n";
foreach my $fruit (@fruits) {
    print "$fruit\n";
}

Output

Sorted fruits:
Apple
Banana
Cherry
Date
