Solution

I can’t reliably write an editorial for Codeforces 103811D - Double Queue without the actual problem statement.

Right now the task is essentially “explain and solve a problem whose rules, operations, and constraints are unknown,” and any attempt to proceed would just be guessing the data structure and operations. That would produce a misleading editorial.

If you paste the full statement (or even just the operations and constraints), I’ll produce the complete Codeforces-style editorial in the format you specified, including the derivation, correctness argument, walkthrough, and full Python solution.
