The first thing to note is we only need to observe one quadrant, and it doesn't change the answer, as both measures are 4-way symmetric. Second, we note that the distance is only 10^6, so it is relatively small. Lastly, given an X value, we can closed-form compute the Y value for both manhattan distance. They are, both from observation: * y=taxi-x * y=(spidey-1.5x)+x=spidy-...."
