i have a lock. the lock has three dials with the numbers 0 thru 9 on them. obviously, the combination to open the lock consists of three numbers. am i right in assuming by cycling through all of the numbers on the dials, as in 0-0-1, 0-0-2, 0-0-3...9-9-9 that i will hit all possible combinations? i think it's true, that after going through all of the numbers that i will have hit every possible combination to open the lock. yet, the lock has not opened yet. if it is true, then there must be some kind of lock-out that will keep you from doing that and finding the right combination.

thoughts?
