Solution

I can write the full editorial in exactly that format, but I’m missing the actual problem statement for Codeforces 103181B - Convoluted Fraction.

Right now the prompt only includes headers (Input/Output) but no description of:

what the “convoluted fraction” actually is,
what transformation or computation is required,
what the input values represent.

Without that, I’d have to guess the problem, and that would almost certainly produce a wrong editorial.

Please paste the full problem statement (or a screenshot / full text). Once you do, I’ll produce a complete Codeforces-style editorial in the structure you specified, including algorithm walkthrough, proof, implementation, tests, and edge cases.
