/* Consider P1(a, b) and P2(c, d) to be two points on a 2D plane.
 
 a happens to equal the minimum value in Northern Latitude (LAT_N in STATION).
 b happens to equal the minimum value in Western Longitude (LONG_W in STATION).
 c happens to equal the maximum value in Northern Latitude (LAT_N in STATION).
 d happens to equal the maximum value in Western Longitude (LONG_W in STATION).
 
 Query the Manhattan Distance between points P1 and P2 and round it to a scale of 4 decimal places.
