Web1. Given an array of integers. Find the Inversion Count in the array. 2. For an array, inversion count indicates how far (or close) the array is from being sorted. If array is already sorted then the inversion count is 0. If an array is sorted in the reverse order then the inversion count is the maximum. 3. WebInversion is a case in which for two integers i < j, i th element in the array is larger than j th element. If the array consists of (2,3,8,6,1), we can find five inversions of (2,1), (3,1), (8,6), (8,1), and (6,1). The simplest and easiest way is to compare all the pairs in the array.
