I have three arrays such as below. What I want to do is if the element inside the arrays match, then it will do something. How do I correct this code? 
@input_array = N1 N2 N3 N6 N7
@input_A = N1 N3 N11 N11 N10 N16
@input_B = N3 N6 N2 N7 N16 N19

   if (grep { @input_B eq $_ } @input_array) 
   {
       if (grep { @input_A eq $_ } @input_array)
       {
        foreach my $inputKey (@input_array)
        {
            @{$primaryCC0{$inputKey}} = (1,1); # each key of the hash 
+has an array with 2 values
        } 
        
        foreach my $key (sort keys %primaryCC0) # to display value CC0
+ and CC1
        {
            my ($CC0, $CC1) = @{$primaryCC0{$key}};
            print "CC0[$key] = $CC0\n";
            print "CC1[$key] = $CC1\n\n";
        }    
       }
       else
       {print "only 1 input is PI";}
   }
   else
   {print "this is a wire\n\n";}
