[Solved]Let S Array N Elements Total Order Relation Defined Inversion S Pair Indices J S J Descri Q37115422

Let S be an array of n elements on which a total order relationis defined. An inversion in S is a pair of indices i and j suchthat i S[j]. Describe an algorithm running in O(n log n) time fordetermining the number of inversions in S (which can be as large asO(n^2)).

Hint: Try to modify the merge-sort algorithm to solve thisproblem
