Here's another option:
use Modern::Perl;
use Data::Dumper;
my @array = qw/1 A 2 B 3 C 4 D 5 E/;
my $i = 0;
say 'Before:';
say Dumper \@array;
@array = grep !($i++ % 2), @array;
say 'After:';
say Dumper \@array;
Outout:
Before:
$VAR1 = [
'1',
'A',
'2',
'B',
'3',
'C',
'4',
'D',
'5',
'E'
];
After:
$VAR1 = [
'1',
'2',
'3',
'4',
'5'
];
This uses the modulo operator within grep to let only the even-numbered elements of the array pass.
Hope this helps!
