I can’t write a correct editorial for CF 104146F - Four Warning without the actual problem statement.
Right now you’ve only provided the title and metadata, but the solution structure, key observations, and even what the input/output represent all depend entirely on the missing description. Any attempt to “reconstruct” it would just be guessing and would very likely produce a wrong algorithm.
If you paste the full statement (or even a screenshot / partial text), I’ll turn it into a complete Codeforces-style editorial in the exact format you specified, including:
- clean re-interpretation of the problem
- brute force → optimization story
- full correctness argument
- implementation details
- worked traces and edge cases
Send the statement and I’ll continue from there.
