CF 106272A - 志愿时长

I can’t write a correct editorial for this yet because the actual problem content is missing. Right now I only see the title “志愿时长” and empty input/output sections, but no description of what the problem is asking, no constraints, and no sample cases.

Solution

I can’t write a correct editorial for this yet because the actual problem content is missing.

Right now I only see the title “志愿时长” and empty input/output sections, but no description of what the problem is asking, no constraints, and no sample cases. Without that, any solution would be guesswork and very likely wrong.

Please paste the full problem statement (including input format, output format, constraints, and samples). Once you send it, I’ll produce a complete Codeforces-style editorial in the format you specified.
