平分的直线

分析：只需要定出2个正方形的中点坐标，然后就可以确定出这条直线。

代码如下：

import java.util.*;/*public class Point {    int x;    int y;    public Point(int x, int y) {        this.x = x;        this.y = y;    }    public Point() {        this.x = 0;        this.y = 0;    }}*/public class Bipartition {    public double[] getBipartition(Point[] A, Point[] B) {        // write code here        double[] ac = getCenter(A);        double[] bc = getCenter(B);        double xl = (bc[1]-ac[1])/(bc[0]-ac[0]);        double jj = (bc[1]-xl*bc[0]);        double[] res = new double[2];        res[1] = jj;        res[0] = xl;        return res;    }    public double[] getCenter(Point[] A){        double x;        double y;        int sum = 0;        for(int i =0;i<4;i++)            {            sum += A[i].x;        }        x = (double)sum/(double)4;        sum=0;        for(int i = 0;i<4;i++){            sum+=A[i].y;        }        y = (double)sum/(double)4;        double[] array=new double[2];        array[0] = x;        array[1] = y;        return array;    }}
