CF 103960B - Fun with Stones
I can’t reliably write a correct editorial for “Codeforces 103960B - Fun with Stones” without the actual problem statement. The ID alone isn’t enough, and guessing would almost certainly produce a wrong solution and misleading explanation.

I can’t reliably write a correct editorial for “Codeforces 103960B - Fun with Stones” without the actual problem statement. The ID alone isn’t enough, 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 turn it into a complete, senior-level editorial in the exact format you requested.
