How to Reverse an Array in Perl ?

Answer

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

✐ Examples

1 Reverse Array of Integers

In this example,

We have an array named @int_array containing integers.
We use the reverse function on @int_array to reverse the elements.
We print the reversed array to demonstrate the reversal.

Perl Program

@int_array = (1, 2, 3, 4, 5);
@reversed_array = reverse @int_array;
print "Reversed Array: [@reversed_array]\n";

Output

Reversed Array: [5 4 3 2 1]

2 Reverse Array of Strings

In this example,

We have an array named @str_array containing strings.
We use the reverse function on @str_array to reverse the elements.
We print the reversed array to demonstrate the reversal.

Perl Program

@str_array = ("apple", "banana", "cherry");
@reversed_array = reverse @str_array;
print "Reversed Array: [@reversed_array]\n";

Output

Reversed Array: [cherry banana apple]
