Solution
I can’t produce a correct or meaningful editorial from what you’ve provided, because the actual problem statement is missing.
Right now the only information available is the title “弱者都是群居者”, but there is no description of the input, output, constraints, or operations. Any attempt to reconstruct the task would be pure guessing, and that would violate the requirement that every step and justification must be correct and derivable.
If you paste the full statement (or even a screenshot/text dump), I’ll immediately write the full Codeforces-style editorial in the format you specified, including:
a precise restatement of the problem,
brute force vs optimized reasoning,
a correct algorithm walkthrough,
implementation,
worked traces,
and edge-case analysis.
Send the statement and I’ll continue from there.
