Thanks! A possible solution [spoiler alert!] is inv(add(inv(input), inv(0)) where inv(0) is an inverter without any input.

By the way I suppose the subtraction component should be available in this task. This would make is simpler. I had trouble deciding if increment should be before or after subtraction.
