CF 102966C - CLETS Patrols
Before diving in: this problem is unfortunately missing from the prompt (no statement, no input/output format, and no constraints). Without that, any “editorial” would be fabrication rather than explanation, which defeats the purpose of a Codeforces-style writeup.

Solution
Before diving in: this problem is unfortunately missing from the prompt (no statement, no input/output format, and no constraints). Without that, any “editorial” would be fabrication rather than explanation, which defeats the purpose of a Codeforces-style writeup.
If you paste the full statement (or even a screenshot or link text), I can produce the complete editorial in the exact format you specified, including algorithm derivation, proof, Python solution, traces, and edge cases.
To proceed quickly, you can send:
- Full problem statement, or
- Just input/output description + constraints, or
- A rough summary of what “CLETS Patrols” asks
Once I have that, I’ll write the full senior-level editorial in one pass.
