in reply to error message in the end of the array looping?

Use the first() function from List:Util .

print +(first { $_ eq 'correct_value' } @arr) || 'not found';

    Alternatively, if you can get your hands on it, List::MoreUtils has a bunch of small, but useful subroutines.
    -----------------------------

    use List::MoreUtils qw(any); ... print "Success" if any { $_ eq "correct_value" } @hash{@array};

    -----------------------------
    Notes:
    1 - note the use of a hash slice; it takes some getting used to, having a @ instead of a % in front.
    2 - please use something more meaningful than %hash or @array as var names in your actual code :)
