 - ~~arc117_d: Immediately reminds us of centroids/diameters, but don't get confused because this a diameters problem, make sure you read the conditions in the problem carefully as well~~
 
-- arc123_d: Do some test cases and there's an obvious greedy strategy; However, reading it closely, it's actually asking for the absolute value, so we should try all of the shifts; You can binary search or two-pointers, but the easiest way is to put all the shifts into an array and sort them, then go through the one by one
