Print the given list in reverse order.
Start with an array of integer numbers.
my @a = (10, 20, 30, 40, 50);
To reverse the array, call the reversemethod on it.
This line prints the required result:
(50 40 30 20 10)
Notice that the initial array stays unchanged. The reversemethod creates a new sequence and returns it.
The same method works with other types of data that can be converted to a sequence, for example, ranges.
Print a range in reversed order:
my $range = 10..15;
Again, the original range is not changed, and the returned value is not a range but a sequence. Compare the results of printing an original value of
$range with what the
reverse method returns:
(15 14 13 12 11 10)
