Can this be explained without hash tables in simple terms please?

(20 points) Let A[1..n] be an array of positive integers (A is not sorted). Pinocchio claims that there exists an O(n)-time algorithm that decides if there are two integers in A whose sum is 1000. Is Pinocchio right, or will his nose grow? If you say Pinocchio is right, explain how it can be done in O(n) time; otherwise, argue why it is impossible
