1. Merge sort array A and create a copy (array B) 2. Take A[1] and find its position in sorted array B via a binary search. The number of inversions for this element will be one less than the index number of its position in B since every lower number that appears after the first...
Apply coordinate compression on the first element of pairs (for using them as index). Create a mergeSort-tree initialized to −∞−∞ While iterating through the array: update(pair.first[index],pair.second[value]) Query for number of elements whose value > pair.second in the range [0...
