### Problem Statement

You are given an even number of points in the plane. You want to find a rectangle whose corners have integer coordinates and sides are parallel to the axes, such that at least half of the given points lie in the interior of the rectangle. Return the area of the smallest such rectangle. ("Smallest rectangle" means the rectangle with the smallest area.) Note that if a point lies on the edge of the rectangle, it does not count as being in the interior.

The input is formatted as follows. You are given String[] X and String[] Y. The first thing that you should do is concatenate the elements of X to form a single String. This String contains up to 100 integer numbers without extra leading zeroes, each separated by one or more spaces. The ith number in this String is the x-coordinate of the ith point. Similarly, you should concatenate the elements of Y to form a single String. That String also contains up to 100 integer numbers without extra leading zeroes, each separated by one or more spaces. The ith number in this String is the y-coordinate of the ith point.

### Definition

 Class: EnclosingRectangle Method: smallestArea Parameters: String[], String[] Returns: int Method signature: int smallestArea(String[] X, String[] Y) (be sure your method is public)

### Notes

-If a point lies on the edge of a rectangle, it does not count as being in the interior of that rectangle.

### Constraints

-X contains between 1 and 50 elements, inclusive.
-Each element of X is a String which contains between 0 and 50 characters, inclusive. Each character is a digit ('0'-'9') or a space (' ').
-The String formed by concatenating the elements of X has no leading or trailing spaces, and consists of a list of integer numbers separated by one or more spaces. Each number in the list is between 0 and 10000, inclusive, and has no extra leading zeroes.
-Y contains between 1 and 50 elements, inclusive.
-Each element of Y is a String which contains between 0 and 50 characters, inclusive. Each character is a digit ('0'-'9') or a space (' ').
-The String formed by concatenating the elements of Y has no leading or trailing spaces, and consists of a list of integer numbers separated by one or more spaces. Each number in the list is between 0 and 10000, inclusive, and has no extra leading zeroes.
-The number of integers represented in X is the same as the number of integers represented in Y, which is an even number between 2 and 100, inclusive.
-All points are distinct.

### Examples

0)

 { "100 200" } { "100 200" }
Returns: 4
 We have two points (100,100) and (200,200). One way to enclose at least one point is to have the rectangle with opposite corners at (99,99) and (101,101). The area of this rectangle is 4.
1)

 { "10 11 13 10 11 13" } { "5 5 5 15 16 17" }
Returns: 10
 We have six points (10,5), (11,5), (13,5), (10,15), (11,16), (13,17). The rectangle with opposite corners at (9,4) and (14,6) encloses the first three points. It turns out that no smaller rectangle can enclose at least three of the six given points. The area of this rectangle is 10.
2)

 { "5 6 6 7 7 8 8 9" } { "7 6 8 5 9 6 8 7" }
Returns: 16
 These points form a diamond shape
