三个数组求中位数，以及中位数的中位数----java算法实现

求三个数组的中位数，以及中位数的中位数。

 

import java.util.Arrays;



public class median {

public static void main(String[] args) {



//m=3,n=3

long[] a = {1,2,6,4,5,9};

long[] b = {3,9,23,51,5};

long[] c = {13,234,1,54,32};





Arrays.sort(a);  //用来排序的方法

Arrays.sort(b);

Arrays.sort(c);



long aa = med(a);

long bb = med(b); 

long cc = med(c);





System.out.println(aa);

System.out.println(bb);

System.out.println(cc);



long[] d = {aa,bb,cc};

Arrays.sort(d);

long dd = med(d);



System.out.println(dd);



}



public static long med(long[] a)

{

long m = 0;

int len = a.length;

if(len%2==0)

{

m = (long) ((a[len/2] + a[len/2-1])/2.0);

}

else 

{

m = a[(len-1)/2];

}

return m;

}
