    Just a friendly reminder. Please use English. Some ppl mentioned the language problem before, as LeetCode is an international platform, you are more welcomed to use an international language. :)
    And I do not think that is a big problem. As you said, the range of each number is from 1-9. If the algorithm is correct for all the cases of 1-9, it is OK.
