I hacked several solutions of 1498B - Box Fitting in an attempt to help kill $O(n^2)$ solutions which utilise the $O(n)$ erase operation of a vector and also to kill slow solutions that does memset of a large array for each test case.

From my understanding, whenever there is a successful hack, the corresponding hack test case should be added to the system tests.

I submitted 111631567 after I made the successful hack with hack id 717894, yet the successful hacks from hack id 717866 to 717894 inclusive in 1498B - Box Fitting are not included in the system tests.

Is this a feature or a bug?
