#include <stdio.h>

//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);
}

count++;
}
