Solution

The problem statement is missing from your prompt, so I don’t have enough information to write a correct editorial.

“Codeforces 104656D1 - Contransmutation D1” alone isn’t sufficient to reconstruct the task, constraints, or required output, and guessing would almost certainly produce a wrong solution and misleading explanation.

If you paste the full statement (or even just input/output description plus constraints), I’ll produce the complete Codeforces-style editorial in the exact format you specified.
