WebDec 7, 2024 · Inversion Count for an array indicates – how far (or close) the array is from being sorted. If the array is already sorted, then the inversion count is 0, but if the array is sorted in the reverse order, the inversion count is the maximum. Formally speaking, two elements a [i] and a [j] form an inversion if a [i] > a [j] and i < j Example:
WebSep 5, 2024 · 1 Answer Sorted by: 0 As gfg uses many test cases to check your code , the answer that you get on the first test cases gets hold to the static variable (count) and will never be reset.

Ans, res = 0, for storing the number of inversions in an array. Now, run a loop i from the last element of the array to the front. And check, if arr [i] = 0, then, Increment count by 1. Else, Add count in res. darwin chemical companyWebJul 20, 2024 · On the above example, this algorithm works like this-. a [] = {7, 3, 2, 4, 1}, k = 3; Inversion are counted for first subarray A = {7, 3, 2} Let this be equal to invcount_A. For counting the inversion of subarray B we subtract the inversion of first element of A, from invcount_A and add inversions of 4 (last element of B) in the subarray B.
