Q3: Given a sequence of numbers a1,dots,an, find the number of weighted inversions. Two
indices i and j form a weighted inversion if ai>2ajO(nlogn)i and ai>2aj. You need to design anO(nlogn)
divide-and-conquer algorithm to solve this problem. Detailed pseudocode and runtime analysis
is required. [5 points]
