you could use the conditional operator aka "ternary operator" :

my @cell_contents = map { $_ ? 1 : 0 } @$array_ref[3..10];

another idea is to use doubled negation "!!" and to map the empty string (false) to 0.

my @cell_contents = map { 0 + !!$_ } @$array_ref[3..10];

but I don't think this conciseness justifies the loss of readability.¹

¹) well if you really need 0 for false.
