 - ~~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~~
