Solution
The problem statement for “Codeforces 103107D - Doin' Time” is not included in your message, so I can’t reliably derive the solution or write a correct editorial.
This matters because Codeforces problems are highly specific, and even small differences in rules (transitions, constraints, or what is being optimized) completely change the intended technique. If I guessed, the editorial would likely be wrong or misleading.
Paste the full statement (or even a screenshot / text dump), and I’ll produce the complete editorial in the exact format you requested.
