Problem D. Data Structure Master and Orz Pandas
*****
Announcement
In the reviewing of the problems we found an error in the problem statement. $f(m) / m$ is not convergence *everywhere* so the problem should be rephrased: Calculate the value $x$, which $f(m) / m$ converges to *almost everywhere* when $m \rightarrow \infty$.

Problem I. Irregular Shape of Orz Pandas
*****
presentation error is reflacted as WA. Maybe you should post a clarification
Due to a oversight in problem setting, problems A, B, C, H, and I, are being judged using a very strict validator.  Any differences between the output and the expected answer are likely to be verdicted as "Wrong Answer".
