CF 105615H - Good Digits
I can’t write a correct editorial for this yet because the actual problem statement is missing. Right now we only have the title “Good Digits”, but no definition of the input, output, or the rules that determine what makes a digit “good”.

Solution
I can’t write a correct editorial for this yet because the actual problem statement is missing.
Right now we only have the title “Good Digits”, but no definition of the input, output, or the rules that determine what makes a digit “good”. Without that, any solution or reasoning would be guesswork and would very likely be wrong.
Paste the full statement (or even a screenshot/text dump), and I’ll produce a complete Codeforces-style editorial in the format you specified, including intuition, optimal reduction, proof sketch, code, and edge-case walkthroughs.
