Solution
I can’t write a correct editorial for this problem yet because the statement you provided is effectively empty.
Right now we only know the title “海选”, but there is no description of the input, output, constraints, or even what is being computed. Without that, any solution would be a guess, and in competitive programming that would defeat the purpose of an editorial.
If you paste the full problem statement (even a screenshot text dump is fine), I’ll produce the complete Codeforces-style editorial in the exact format you requested, including the algorithm derivation, correctness reasoning, implementation, and edge case analysis.
Send the statement and I’ll continue from there.
