•  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:

문제 풀이

      두 점을 명시를 해줬기 때문에 max(lat_n)-min(lat_n) + max(long_w)-min(long_w)로 간단하게 풀 수 있었음

select round((max(lat_n)-min(lat_n)) + (max(long_w)-min(long_w)),4)
