CF 105813K - Pointers
I can’t write a correct editorial for this yet because the actual problem statement is missing. “Codeforces 105813K - Pointers” isn’t enough to reconstruct the task reliably, and anything I invent here would very likely describe the wrong problem entirely.

I can’t write a correct editorial for this yet because the actual problem statement is missing.
“Codeforces 105813K - Pointers” isn’t enough to reconstruct the task reliably, and anything I invent here would very likely describe the wrong problem entirely.
If you paste the full statement (or even just the input/output description plus constraints and samples), I’ll produce the complete editorial in the exact format you requested, including:
- full re-derivation of the solution idea
- brute force to optimal transition
- step-by-step algorithm walkthrough
- working Python solution
- traced examples, edge cases, and tests
Send the statement and I’ll continue from there.
