I would like to ask about 2 dimensional array
Each element of a Perl array is a scalar.
my @colors = ( "red", "white", "blue" );
which can also be written as:
my @colors = qw( red white blue );
and can be used as:
print "ok" if $colors[ 2 ] eq "blue";
An array-reference is a scalar:
my @colors_2d = (
[ qw( red white blue ) ],
[ qw( black red green ) ],
);
print "ok2" if $colors_2d[ 0 ][ -1 ] eq "blue";
