For a real world lock, the key height + pin height must equal the height of the barrel exactly. If it is taller or shorter, the lock will bind and not open.

For the challenge, as long as its not overlapping (too tall), its a valid key/lock pair.
Oh! I didn't think it that way, lol, I was thinking this quickly through. I didn't think of relating to physical locks because it clearly said it was virtual. But I guess, there could theoretically be a physical tumbler lock with 0-5 spacers, it would just be a tall lock. You know like how some master keys have it so that there are spacers for the master key or the client key to open the lock.
