igate Test Series
Rahul knows the implementation of merge sort. One day, his teacher asked him to find numbers of inversion in an array. An inversion can be defined in an array as if i < j, a[i] > a[j] then it is an inversion. Now, given there are p inversions in an ... multiply all elements by -1, what is the time complexity to find inversions in an updated array? O(n) O(nlogn) O(n^2) None
