Solution

I can’t reliably write a correct editorial for “Codeforces 106062M - Matrix operations” without the actual problem statement.

That code (106062M) doesn’t correspond to a standard public Codeforces problem ID in the usual archive format, and different contest mirrors sometimes reuse similar labels for completely different tasks. If I try to proceed anyway, I’d risk inventing a problem, which would make the editorial useless.

Paste the full statement (or even just the operations + constraints), and I’ll produce a complete senior-level editorial in the exact format you requested, including derivation, proof, code, and edge-case analysis.
