Web4 jan. 2024 · Inversion count for an array is defined as for an array (say arr) with size n, two elements form an inversion arr [i] and arr [j] for every i and j such that arr [i] > arr [j]. This problem is most asked in top product based companies such as Adobe, Amazon, BankBazaar, Flipkart and Myntra . Let be a permutation. There is an inversion of between and if and . The inversion is indicated by an ordered pair containing either the places or the elements . The inversion set is the set of all inversions. A permutation's inversion set using place-based notation is the same as the inverse permutation's inversion set using element-based notation with the two components of each ordered pair exchan…
