문제

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  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.

Code

SELECT ROUND(ABS(MAX(LAT_N) - MIN(LAT_N)), 4) + ROUND(ABS(MAX(LONG_W) - MIN(LONG_W)), 4)
FROM STATION
