CF 104688B3 - Prime Time B3
The prompt is missing the actual Problem Statement / Input / Output description for “Codeforces 104688B3 - Prime Time B3”. Without that, I can’t correctly reconstruct the logic, constraints, or solution approach, and any editorial would be guesswork.

The prompt is missing the actual Problem Statement / Input / Output description for “Codeforces 104688B3 - Prime Time B3”.
Without that, I can’t correctly reconstruct the logic, constraints, or solution approach, and any editorial would be guesswork.
Please paste the full problem statement (or a link + key details), and I’ll produce the complete Codeforces-style editorial in the exact format you specified.
