Problem

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  decimal places.

Input Format

The STATION table is described as follows:

FieldType
IDNUMBER
CITYVARCHAR2(21)
STATEVARCHAR2(2)
LAT_NNUMBER
Long_WNUMBER
STATION

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