Solution
The statement you pasted only contains the title “I. 算术” with empty input and output sections, so there is no information about what the problem is actually asking to compute.
To write a proper Codeforces-style editorial, I need at least one of the following:
The full problem statement (what operations are involved, what is given in input, what must be output), or
A link or screenshot of the problem content.
Right now there is nothing to reconstruct the algorithm from, so any solution would be guesswork and very likely incorrect.
If you paste the full statement, I can immediately produce the complete editorial in the exact format you requested.
