Solution
I cannot produce a correct editorial for Codeforces 105788E - Captivity yet because the actual problem statement is missing, and it is not retrievable from the provided context or standard public mirrors.
What I need to proceed is the full statement (or at least a reliable summary of rules, input/output, and constraints). Right now, only the problem name is known, which is not enough to reconstruct the logic safely. Any attempt to “guess” would almost certainly produce a wrong solution and a misleading editorial.
If you paste the statement here, I will immediately write a full Codeforces-style editorial in the exact format you requested, including:
a clean restatement, derivation of the key idea from brute force, correctness argument, implementation details, traces, and tests.
Just send the problem text or a screenshot transcription.
