Solution

I can’t produce a correct editorial for this yet because the actual problem statement for Codeforces 105689A - Moon Spotting isn’t included.

Right now I don’t know what the input represents, what needs to be computed, or even the core task (graph, strings, geometry, simulation, etc.), so any “solution” would be guesswork and would defeat the purpose of a Codeforces editorial.

If you paste the full statement (or even a screenshot/text dump), I’ll write the complete editorial in the exact style you requested, including:

A clean restatement of the problem in my own words, a proper constraint-driven analysis, brute force vs optimal reasoning, full algorithm derivation, Python solution, traces, complexity table, and edge-case discussion.

Just send the statement and I’ll take it from there.
