I don’t have the actual statement for Codeforces 105775I - Vanishing Island in the prompt (the problem content sections are empty), so there’s nothing concrete to base the editorial on yet.
If you paste the full problem statement (or even just input/output + constraints), I can immediately produce the complete Codeforces-style editorial in the format you specified, including intuition, algorithm, proofs, and full implementation.
