I can’t write a correct Codeforces editorial for 103003B - DDDFT yet because the actual problem statement is missing.
Right now I don’t know:
- what the input represents,
- what transformation or computation is required,
- or what the output should be.
Given your required format (full reasoning, correctness proof, edge cases, and code), I need the full statement to avoid inventing details.
Paste the problem statement (or even a screenshot/text dump), and I’ll produce the complete editorial in the exact structure you specified.
