Solution

I can’t write a correct editorial for this yet because the actual problem statement is missing.

“Codeforces 103109E - Knockout Tournament” isn’t enough on its own to reconstruct the rules, and anything I write without the full description would be guesswork (which would defeat the point of a rigorous editorial).

Please paste the full problem statement (or even a screenshot / raw text). Once you do, I’ll produce the complete Codeforces-style editorial in the exact format you specified, including:

Clean restatement of the tournament mechanics
Correct optimal solution derivation from brute force
Full algorithm walkthrough with invariants
Working Python implementation
Sample traces, edge cases, and complexity proof

Send the statement and I’ll proceed immediately.
