Count number of arrays with k-inversions

Revision en1, by aakarshmadhavan, 2018-08-09 07:59:46

I'm trying to come up with a recursive solution for this problem but I haven't been able to so far. Any advice/pointers here?

I tried 0-1 knapsack style but there is an issue with backtracking the array.
