The system for selling cinema tickets calculates the discount type based on the client’s birth year (BY) and on the current year (CY) as follows:

Let D be the difference between CY and BY, that is, D = CY - BY

If D < 0, then print the error message "birth year cannot be greater than current year"
If 0 ≤ D < 18, then apply the student discount
If 18 ≤ D < 65, then apply no discount
If D ≥ 65, then apply the pensioner discount

Your test suite already contains two test cases:

Which of the following test data sets should be added to achieve full valid equivalence partitioning coverage for the discount type?
