[int(x) for x in input().split()] is the same as list(map(int, input().split()))
To make use of input_n you would have to modify def max_pairwise_product(numbers): to add another parameter, say n as def max_pairwise_product(numbers, n): so that in the function body you'd remove n = len(numbers).
So you would add another parameter, n and remove the line, n = len(numbers)

nand remove the line,n = len(numbers)Yes. Thank you for the suggestion.
