Perl arrays are powerful and flexible data structures that allow you to store ordered lists of elements. In terms of performance, Perl arrays are generally efficient for a variety of operations, including indexing, pushing/populating data, and iterating over elements. However, the performance can vary depending on factors such as the size of the array and the complexity of the operations being performed.
#!/usr/bin/perl
use strict;
use warnings;
my @array = (1..1000000); # Creating an array with 1 million elements
# Measuring the time taken to access an element
my $start_time = time();
my $element = $array[999999]; # Access the last element
my $end_time = time();
print "Accessed element: $element\n";
print "Time taken: ", $end_time - $start_time, " seconds\n";
# Measuring the time taken to push an element into the array
$start_time = time();
push(@array, 1000001);
$end_time = time();
print "Pushed new element: 1000001\n";
print "Time taken: ", $end_time - $start_time, " seconds\n";
