Sample Solution:
Java Code:
import java.util.LinkedList;
public class Example23 {
public static void main(String args[])
{
for (int i = 1; i < 1000; i++) {
int n = i;
LinkedList<Integer> data = new LinkedList<>();
while (n > 0) {
data.push( n % 10 );
n = n / 10;
}
int n1 = 0;
for(Integer num : data) {
n1 += Math.pow(num, data.size());
}
if(i == n1) {
System.out.println(i);
}
}
}
}
Sample Output:
1 2 3 4 5 6 7 8 9 153 370 371 407
