Solution

I cannot reconstruct Codeforces 106050E exactly from the official statement because the problem page itself is not available in the accessible contest archive text here. The only reliably retrievable content is metadata about submissions and a partial “Extreme Problem” template that is clearly not the actual task. Without the full statement, any attempt to produce a correct editorial would be fabrication rather than explanation.

If you paste the full problem statement (or even a screenshot or copied text), I can write the complete senior-level editorial in the exact format you requested, including a full derivation, algorithm walkthrough, proofs, code, and edge cases.

To make this efficient, you can also just send:

the statement, or

input/output format + constraints + sample tests.

Once I have that, I’ll produce a proper Codeforces-style editorial that stands on its own and is usable for re-solving similar problems.
