Solution

I’m missing the actual problem statement for Codeforces 103967C - “Защитное поле”, so I can’t reliably reconstruct the solution or write a correct editorial.

Right now the sections for input, output, and constraints are empty, which usually means one of the following:

the statement wasn’t pasted, it got truncated, or it was removed from the prompt.

To produce a proper editorial in the format you requested, I need at least:

the full description of the grid/array/graph, the operation or query definition, and the constraints.

Paste the full problem statement and I’ll write the complete editorial in the exact style you specified.
