水仙花数

春天是鲜花的季节,水仙花就是其中最迷人的代表,数学上有个水仙花数,他是这样定义的:“水仙花数”是指一个三位数,它的各位数字的立方和等于其本身,例如:153 = 1 ^ 3 + 5 ^ 3 + 3 ^ 3。现在要求输出所有在m和n范围内的水仙花数。
import java.util.*;public class Main {   	public static void main(String[] args) {   		Scanner sc=new Scanner(System.in);		while(sc.hasNext()) {   			int m=sc.nextInt();//始			int n=sc.nextInt();//末			int arr[]=new int[n-m];			int num=0;//是水仙花数的个数			for(int i=m;i<=n;i++) {   				int a=i/100;//得到百位				int b=i/10%10;//得到十位				int c=i%10;//得到个位						if((a*a*a+b*b*b+c*c*c)==i) {   					arr[num++]=i;				}			}			if(num==0) {   				System.out.println("no");			}else {   				for(int j=0;j
