What are all the possible lock combinations?

The total number of possible lock combinations depends on the number of digits and the range of each digit. For a standard 3-digit lock using numbers 0-9, there are 10 options for each digit, resulting in 1,000 possible combinations (000 to 999). If the lock has a different number of digits or uses letters, the calculation would vary accordingly. For example, a 4-digit lock would have 10,000 combinations.
