    On first glance I figured "a number n" wasn't a specific n (as in "a number, n" or "the number n") but any of the given numbers. You'd ensure they all individually resolve with their respective "other" numbers.

    It's definitely not something someone should get stuck on, but it confused at least one other person for a moment as well.

    It is not very clear that the first given number is the test case. I at first assumed every n had to validate with every other n.

    It took me a glance at the examples to understand what was being asked.
