I can’t safely write a correct editorial yet because the problem statement for Codeforces 106331E is not included, and this ID does not resolve unambiguously to a single known problem from standard archives.

Solution
I can’t safely write a correct editorial yet because the problem statement for Codeforces 106331E is not included, and this ID does not resolve unambiguously to a single known problem from standard archives.
Without the statement, any “solution” would risk being fabricated or mismatched to a different problem (which is exactly what tends to happen when Codeforces gym IDs overlap or are mistyped). The structure, constraints, and even the intended technique depend heavily on the exact task.
If you paste the full statement (or even a screenshot or rough description), I’ll produce a complete, Codeforces-style editorial in the exact format you requested: full reasoning, algorithm walkthrough, proof sketch, Python solution, traces, and edge-case discussion.
Just send the statement and I’ll continue from there.
