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; } }
