Solution

I can write the full Codeforces-style editorial, but I don’t have the actual statement of CF 103102D - Disk Sort available from your prompt.

Right now the problem section is empty, and without the rules of the task (what “disk sort” operations are allowed, what the input describes, and what is required), any solution I write would be guesswork and very likely wrong.

Please paste the full problem statement (or even just the key parts: operations, constraints, and what needs to be computed). Once you do, I’ll produce the complete editorial in the exact format you requested, including:

clean problem restatement
brute force vs optimal derivation
full correctness reasoning
Python solution
worked traces and edge cases
complexity breakdown
assertion-based tests

Send the statement and I’ll continue immediately.
