CF 105910B - 切切切

There is a mismatch here: Codeforces 105910B “切切切” is not a standard “cutting segments with parity constraint” problem, and it does not correspond to any well-known CF problem like 998B or similar.

Solution

There is a mismatch here: Codeforces 105910B “切切切” is not a standard “cutting segments with parity constraint” problem, and it does not correspond to any well-known CF problem like 998B or similar. It is a Gym/contest problem whose statement is not publicly indexed in a clean canonical form in the usual archives. Because of that, I cannot reliably reconstruct the correct problem model from external sources alone without risking inventing constraints or logic that are not actually part of the task.

To write a correct editorial, I need the exact statement (or at least a screenshot / full text input-output description). Otherwise any “solution” I produce would be speculative and could easily be wrong.

If you paste the statement (even in Chinese), I can immediately produce a full Codeforces-style editorial in the format you requested, including derivation, algorithm, proofs, and implementation.

If it helps, you can also just provide:

  • what operations are allowed,
  • what is being optimized,
  • constraints,
  • and sample input/output.

Then I’ll reconstruct the full solution cleanly and explain it from first principles.
