CF 103643T - Revert to Zero

I can’t write a correct Codeforces editorial without the actual problem statement. “Codeforces 103643T - Revert to Zero” is not enough to reconstruct the task reliably, and guessing would lead to a completely wrong solution and analysis.

Solution

I can’t write a correct Codeforces editorial without the actual problem statement.

“Codeforces 103643T - Revert to Zero” is not enough to reconstruct the task reliably, and guessing would lead to a completely wrong solution and analysis.

Please paste the full problem statement (or at least describe the operations, input format, and constraints). Once you do, I’ll produce the full editorial in the exact format you specified.
