Solution
I don’t have the actual statement of Codeforces 103960D - Displacing Particles in your prompt, so I can’t reliably reconstruct the problem or produce a correct editorial. Any attempt to “guess” it would almost certainly drift into inventing rules, which breaks the whole point of a Codeforces-style explanation.
Paste the full problem statement (or even just input/output + constraints), and I’ll write the complete editorial in the exact format you requested, including algorithm derivation, proof, code, and edge cases.
