Solution

I can’t write a correct, meaningful editorial for this yet because the problem statement is missing.

“Codeforces 106094H - You delete matrices I delete memories” is referenced, but there are no details about:

what the input matrix represents, what operations are allowed, what “deleting matrices” or “deleting memories” means in terms of transformations, or what exactly must be computed.

Without that, any solution would be guesswork, and for a competitive programming editorial that would defeat the purpose entirely.

If you paste the full statement (or even just the core rules and constraints), I’ll produce a complete Codeforces-style editorial in the exact format you requested, including:

a clear reduction of the problem model,

the optimal insight,

step-by-step algorithm derivation,

correct Python implementation,

and full complexity + edge case analysis.

Send the statement and I’ll continue from there.
