Solution

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

“Codeforces 103029C - John, Katya, no nuts” doesn’t include any description of the input/output or the task, and without that there’s nothing concrete to restate, analyze, or derive an algorithm from. Anything I write at this point would be guesswork and would likely be wrong.

Paste the full problem statement (or even a screenshot / text dump), and I’ll turn it into a complete Codeforces-style editorial in the exact format you specified, including:

proper restatement in fresh wording
brute force → optimized transition
full algorithm walkthrough with invariants
working Python solution
traced examples and edge cases

Once you send it, I’ll proceed directly.
