    Guess they didn't like "Div. 1" / no qualifier / "Div. 2" so they went to ++ / no qualifier / --.

Thank you for participating!

I have created many problems so far, and today’s Problem D is my favorite one of all. The problem statement is simple, the solution is amazing, and the implementation is short and clean!

The solution to Problem E is also very interesting, and the implementation can be kept short if done well.

I’m looking forward to your upsolving!

Would be pleased if B doesn't ask for precomputing answers.
