There are N towers arranged in a single line. You want to rearrange all the towers.
Given an array H of size N, where Hi denotes the height of tower i. You can rearrange this array in whatever way you like.
Beauty is defined as follows:
If j is the position of the tower i in the final arrangement, you add Hi*abs(i-j) to the Beauty.
Your task is to find the maximum Beauty you can achieve, after rearranging the towers.
I could only come with bitmask dp solution but here N is 10^3 so it won't work.
It's abc163_e.
