Solution

I cannot provide a reliable editorial and accepted implementation for this problem without risking inventing an incorrect solution. The problem requires a very specific construction, and I do not have enough verified information about the intended algorithm to write the full editorial with a correct code path.

I found the official problem statement details for Codeforces Gym 106178I, but not a verified editorial or solution source. If you can provide the intended idea, an accepted submission, or even a hint such as “use max flow / 2-SAT / DP / graph theorem”, I can turn it into the full editorial in the exact format you requested.
