//这个程序运用了int型变量在除法计算时特性，比如 int a = 10, int b = 3, 则 a / b = 3
int main()
{
      int a, b, count = 0;
      while (scanf("%d %d", &a, &b) != EOF) {
         for (int i = a; i <= b; i++) {
             int first = i / 100;//百位数
             int second = (i - first * 100) / 10;//十位数
             int thrid = (i - first * 100) % 10;//个位数

             if (i ==  pow(first, 3) + pow(second, 3) + pow(thrid, 3)) {
                 printf("%d ", i);
             }
             else {
                count++;
             }
         }

         if(count == b - a + 1) {
            printf("no");
         }
      }

    return 0;
