Solution

I don’t have the actual problem statement for Codeforces 105300K - Sorting Network, and without it I can’t reliably derive the algorithm, constraints, or even the expected I/O format.

This matters a lot here because “sorting network” can refer to multiple very different tasks (verification of a comparator network, constructing a network, simulating layers, minimizing depth, etc.), and each leads to a completely different solution strategy.

If you paste the full statement (or even just the core description plus constraints and samples), I’ll write the complete editorial in the exact format you specified, including the walkthrough, proof sketch, and test suite.
