In the last contest(Codeforces Round 851 (Div. 2)), I wrote a code and did not print Yes 192947512 on problem F.

That's why I got "wrong answer on pretest 2"(pretest 2 is a sample).

And, to my surprise, it is calculated as penalty.

Didn't the original intention of "free to wa on pretest 1" prevent some low-level bugs?

I confess that I didn't check my code carefully.

But in the long run, isn't it against the original intention?

To codeforces's future development, could you please modify this MikeMirzayanov?
