WebOct 31, 2012 · You can count inverted pairs with the algorithm, similar to merge sort, as explained here. The idea is to merge sort the array while counting, how many inversions were changed on each step. A different approach is to use an order-statistics tree. WebNov 27, 2024 · The task is to find inversion count of array. Inversion Count : For an array, inversion count indicates how far (or close) the array is from being sorted. If array is already sorted then inversion count is 0. If array is sorted in reverse order that inversion count is the maximum.
WebThe inversion count concept is used in the array and can be performed using an array data structure. In inversion count, we will specify how we are required to sort an array. We all need to find a couple of elements, for which the first element is always greater than the second one. If an array is already sorted, the total inversion count is 0.
