The problem statement is missing, so I don’t have enough information to reconstruct what 103274B - Basel Problem is actually asking.
“Basel Problem” usually refers to the classic sum $\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}$, but Codeforces tasks with that name often wrap it in a completely different input/output format or computational twist. Without the exact statement, any editorial would be guesswork, and I’d risk explaining the wrong problem.
Paste the full statement (or at least input/output description and constraints), and I’ll write the complete Codeforces-style editorial in the format you requested.
