A with 500 points, the first time in ARC history!
It seems that it has the same time with Codeforces round 927......
This was our first AtCoder writer since ARC 131 (more than 2 years ago). I hope you enjoyed the problem.
Thank you for your participation!
Even though I performed very poorly, the contest was fun :) thank you
might be better to cut CRT solution (precomputing $$$n^n \mod 5^9$$$ for all $$$n \le 4 \cdot 5^9$$$) in E. xD
The time limit of E is too loose that many meet-in-the-middle solutions also passed.
