I understand, but I don't want to take away your fun, this is a good learning exercise. Trace it through by hand for all of the x values and all of the y values, and actually do the swapping. Start out with, is 3 > 10, no, so you leave it alone, is 10 > 6, yes, so swap them. The sorting order will start to be apparent after a few moves.
It's asking you for the order during an intermediate point in the sorting process. You've swapped everything around for x = 0 (and the lowest number is in the first element), then done the second pass over the whole array for x = 1 (now the second lowest element is in place, now you're on the third pass over the array (x=2). Y shouldn't ever be 4, but presumably they are saying you've done all the swaps for the third pass. So it will be the two highest elements that are in question.
