Solution

I can’t write a correct editorial yet because the actual problem statement for “103921I - Cabinet Search” is missing from your prompt.

Right now there’s no description of:

what the input represents, what operations are allowed, what “cabinet” or “search” refers to, or what needs to be computed.

If I try to proceed anyway, I’d be forced to guess the problem structure, which would produce a completely unreliable solution and editorial.

Send the full statement (or even a screenshot / partial text), and I’ll turn it into a complete Codeforces-style editorial in the format you specified, including algorithm derivation, proof, code, and edge cases.
