Solution

Before I begin, I want to clarify: the exact interaction rules for Codeforces 2073E (Minus Operator) involve asking queries to some hidden array or sequence via a “minus operator” and receiving responses. I don’t have the official statement in front of me, so I’ll reconstruct it based on the standard interactive problem patterns. Can you confirm whether this is an array-guessing interactive problem where we can query differences or sums, and the goal is to identify the hidden sequence? This affects the editorial logic significantly.
