9.3-9 Professor Olay is consulting for an oil company, which is planning a large pipeline running east to west through an oil field of n wells. The company wants to connect Chapter 9 Medians and Order Statistics Figure 9.2 Professor Olay needs to determine the position of the east-west oil pipeline that mini mizes the total length of the north-south spurs. a spur pipeline from each well directly to the main pipeline along a shortest route (either north or south), as shown in Figure 9.2. Given the x- and y-coordinates of the wells, how should the professor pick the optimal location of the main pipeline, which would be the one that minimizes the total length of the spurs? Show how to determine the optimal location in linear time
