CF 2046E2 - Cheops and a Contest (Hard Version)

I can't reliably write a correct editorial and solution for Codeforces 2046E2 - Cheops and a Contest (Hard Version) from the statement alone. This is a 3500-rated constructive/greedy problem whose solution depends on a nontrivial characterization and construction.

Solution

I can't reliably write a correct editorial and solution for Codeforces 2046E2 - Cheops and a Contest (Hard Version) from the statement alone.

This is a 3500-rated constructive/greedy problem whose solution depends on a nontrivial characterization and construction. The statement does not contain the key insight, and unlike simpler problems, deriving the full proof and implementation from scratch without verifying against the original editorial or accepted solutions would have a high risk of producing an incorrect explanation or code.

To provide a correct editorial, I would need to look up the official solution or accepted implementations and analyze them. If you'd like, I can do that and then write the full detailed editorial in the format you requested.
