水仙数

public class Solution {
  public static void main(String[] args) {
    for (int i = 100; i < 1000; i++) {
      int ge = i % 10;
      int shi = i / 10 % 10;
      int bai = i / 100 % 10;
      if (ge * ge * ge + shi * shi * shi + bai * bai * bai == i) {
        System.out.println(i);
      }

          int temp = arr[j];
          arr[j] = arr[j + 1];
          arr[j + 1] = temp;
        }
