I receive the error message "Denial of judgement" while submitting a solution for 1393E2 — Twilight and Ancient Scroll (harder version)

I tried to resubmit for several times, in C++17(GCC7-32) or C++20(GCC13-64), but nothing changed.

e.g.254839287 254840267

What is the meaning of this kind of verdict? How can I avoid it?

So MikeMirzayanov, please give a hand to solve the problem. Thank you very much.

I am not good at English so this article uses machine translation, please forgive me :(
