Today in Codeforces Round 244 (Div. 2), I found that there were too many test cases in problems C,D,E.
Problem C and E have more than 100 tests each, and problem D has about 170 tests.
As a result, the system testing phase become very slow.
Do you think that it is necessary to create such many tests? In my opinion, having more than 100 test cases doesn't make the test stronger.
What about you? Thank you.
