 Consider  and  to be two points on a 2D plane.

•  happens to equal the minimum value in Northern Latitude (LAT_N in STATION).
•  happens to equal the minimum value in Western Longitude (LONG_W in STATION).
•  happens to equal the maximum value in Northern Latitude (LAT_N in STATION).
•  happens to equal the maximum value in Western Longitude (LONG_W in STATION).

Query the Manhattan Distance between points  and  and round it to a scale of  decimal places.

Input Format

The STATION table is described as follows:

where LAT_N is the northern latitude and LONG_W is the western longitude.

MySql:
