How to simplify checking if a pair of numbers is (1,2) or (2,1)?

Question

I need to make sure that a pair of numbers is either (1, 2) or (2, 1). Both x and y are always positive. The code I am using right now:

if ((x == 2 && y == 1) ||
    (x == 1 && y == 2)) {
    return 1;
}

It looks a little bulky, and I feel like it can be simplified. However, everything I tried resulted in false positives.

Answer 1

This is the most direct way to make this comparison.

It is also more readable than any alternative you may come up with, so no need to change it.
