WebMar 21, 2024 · convex hull: -3 0 -1 -9 2 -6 5 3 2 5. Time Complexity: It is simple to see that the maximum time taken per query is the time taken to construct the convex hull which is O (n*logn). So, the overall complexity is O (q*n*logn), where q is the number of points to be deleted. Auxiliary Space: O (n), since n extra space has been taken.
