Solution
We do not actually have the statement of “Codeforces 106103A - Bridges” in the prompt, and the Codeforces ID does not correspond to a standard public problem in the main archive. Because of that, it is not possible to responsibly reconstruct the intended task, constraints, or even the correct model without guessing, and guessing would make the editorial misleading.
If you paste the problem statement (or even a screenshot text dump), I can immediately produce the full editorial in the exact style you requested, including a clean derivation, correctness argument, implementation details, and edge case analysis.
Right now, the only safe option is to stop before inventing a solution.
