How to Sort an Array in Perl - Step by Step Examples

How to Sort an Array in Perl ?

To sort an array in Perl, you can use the sort function.

In this example,

@numbers = (5, 2, 8, 1, 6);
sort @numbers;
print "Sorted array in ascending order: @numbers\n";

Sorted array in ascending order: 1 2 5 6 8

In this example,

We create an integer array named @numbers with values 5, 2, 8, 1, 6.
We use the sort function with a custom comparison function that sorts in descending order.
Finally, we print the sorted array @numbers to the console.

@numbers = (5, 2, 8, 1, 6);
sub desc_sort { $b <=> $a }
@sorted = sort desc_sort @numbers;
print "Sorted array in descending order: @sorted\n";

Sorted array in descending order: 8 6 5 2 1
