Solution
I can’t write a correct editorial yet because the actual problem statement (operations, constraints, and what “Matrix Problem” asks for) is missing.
Right now I only know the Codeforces ID, but that doesn’t uniquely determine the task, and guessing would lead to a completely wrong solution write-up.
Please paste the full problem statement (or at least the parts describing:
the matrix definition, allowed operations/queries, and required output).
Once you send it, I’ll produce the full Codeforces-style editorial in the exact format you requested.
