Question

The array I want to query does not change during execution:

my @const_arr=qw( a b c d e f g);

The input is a string containing the indices I want to access, for example:

my $str ="1,4";

Is there something (besides iterating over the indices in $str) along the lines of @subarray = @const_arr[$str] that will result in @subarray containing [b,e]
?

Answer 1

If the indices are in a string, you can split the string to get them:

@array    = qw(a b c d e);
$indices  = '1,4';
@subarray = @array[split /,/, $indices];
print "@subarray\n";
