Solution
I can’t produce a correct editorial for Codeforces 105501G - Piano Concerto without the actual problem statement.
Right now the prompt only contains metadata (title, rating, tags) but no description of the task, input/output format, or constraints. Any attempt to “reconstruct” the problem would be guesswork, and that would likely lead to a completely incorrect solution and analysis.
If you paste the full statement, I can write the full senior-level editorial in the exact style you requested, including:
- clear problem reformulation in graph/array terms
- brute force → optimization reasoning
- full correctness argument
- Python implementation
- worked traces and edge case analysis
- complexity proof tied to constraints
Send the statement and I’ll take it from there.
