i can think of a few ways ...
# loop through the array and check the index
my $index = 1;
for my $value (@array)
{
next if $index%2;
push @only_even , $value;
$index++;
}
# or you can shift two elements and use the last one ...
for my $value (@array) {
# you can also do my ($odd,$even) = splice(@array,0,2);
my $odd = shift @array;
my $even = shift @array;
push @even_only , $even;
}
i did not test the above so use at your own peril ...
