CF 102904C - Электронный замок

I’m missing the actual problem statement (the Input/Output and description are empty), so I can’t reliably reconstruct what “Электронный замок (Electronic lock)” is asking or derive a correct solution.

Solution

I’m missing the actual problem statement (the Input/Output and description are empty), so I can’t reliably reconstruct what “Электронный замок (Electronic lock)” is asking or derive a correct solution.

For Codeforces editorials, even small details like how the lock changes state, constraints on operations, or what constitutes a valid unlock completely determine the algorithm. If I guess here, there’s a high risk of producing a convincing but incorrect editorial.

Please paste the full statement (or at least input format + what needs to be computed). Once you do, I’ll write the complete senior-level editorial in the exact format you specified.
