#### Problem

Considerย P1(a, b)ย andย P2(c, d)ย to be two points on aย 2Dย plane.

• aย happens to equal the minimum value inย Northern Latitudeย (LAT_Nย inย STATION).
• bย happens to equal the minimum value inย Western Longitudeย (LONG_Wย inย STATION).
• cย happens to equal the maximum value inย Northern Latitudeย (LAT_Nย inย STATION).
• dย happens to equal the maximum value inย Western Longitudeย (LONG_Wย inย STATION).

Query theย Manhattan Distanceย between pointsย P1ย andย P2ย and round it to a scale ofย ย decimal places.

Input Format

Theย STATIONย table is described as follows:

whereย LAT_Nย is the northern latitude andย LONG_Wย is the western longitude.
