Counting number of inversions - Code Review Stack Exchange

WebApr 15, 2024 · A simple approach would be to use two nested loops to count the number of global inversions and a single loop to count the number of local inversions.

Run a loop where ‘i’ ranges from ‘0’ to ‘N - 2’: WebOct 25, 2014 · Continuing in this vein will give us the total number of inversions for array A once the loop is complete. Step 1 (merge sort) would take O (n * log n) to execute. Step 2 would execute n times and at each execution would perform a binary search that takes O (log n) to run for a total of O (n * log n).

Inversion count in Array using Merge Sort - GeeksforGeeks

WebNov 9, 2024 · To count the number of inversions, we will use a two pointers approach. Let us consider two pointers i and j, one pointing to the left half and the other pointing towards the right half. While iterating through both the halves, if the current element A [i] is less than A [j], add it to the sorted list, else increment the count by mid – i. WebHey Ninjas!
