Solution

I don’t have the actual statement of Codeforces 103464D “A Task With Queries” in the prompt, so I can’t reliably reconstruct the operations, constraints, or intended solution path.

For a problem with “queries” in the title, there are several completely different possibilities (offline processing, segment tree with lazy propagation, DSU with rollback, BIT with range updates, persistent structures), and writing a full editorial without the exact operations would risk inventing a solution that doesn’t match the task.

If you paste the problem statement (or even just the input format + what each query does), I can produce a complete Codeforces-style editorial in the exact format you requested, including the algorithm walkthrough, proofs, code, and test cases.
