The 8th test case is correct and can be solved within Cody's time limit. Why is it not being used? Up to 200.000, there are 20 amicable pairs.
For instance 176272,180848 is the 20th pair. For 3e5 my code can't go fast enough for Cody (45s), but I've found just 2 additional pairs 196724, 202444 and 185368, 203432.
