CF 105811H - Lineism
I don’t actually have the problem statement for Codeforces 105811H - Lineism in your prompt (it’s blank), so there’s no way to correctly reconstruct the task, constraints, or intended solution.

Solution
I don’t actually have the problem statement for Codeforces 105811H - Lineism in your prompt (it’s blank), so there’s no way to correctly reconstruct the task, constraints, or intended solution.
For a Codeforces editorial, the structure and even the algorithm depend heavily on the exact definitions in the statement (what “Lineism” refers to, what operations are allowed, what needs to be computed). Without that, any “solution” would be guesswork and very likely wrong or misleading.
If you paste the full statement (or even just input/output + constraints), I can immediately write the full senior-level editorial in the exact format you requested, including:
- clean problem restatement
- brute force vs optimal transition
- formal invariant-based correctness argument
- full Python solution
- traced examples, edge cases, and tests
Send it over and I’ll produce the complete write-up.
