C++20: 304481417 TLE. Then I run it in mushup contest to see it's real running time.

What the hell is the Div2 last night? It had A $$$\to$$$ E having much less difficult of thinking than before with a quite hard but typical(I heard from those who got accepted) F(actually ex $$$\to$$$ G)) math problem. I just thought I was do a ABC.

Help! The time complexity of my code is $$$O(n\log^2V+q\log V),V=10^9$$$.

I found that there are too many "1" in the data, and I made a piece of data like that, but my code just run for 0.3s.
