After implementing top-down algorithm as #41, I'm still not sure that this is enough to pass all the tests, including bottom-up algorithm. I think my bottom-up algorithm may suffer from test cases with many rows, and there may be no exception for other students.
I think it would be better if there's a guideline for other test cases. For example, the maximum number of examples in one csv file, or the maximum number of terms in answers.
