C++ :

#include<iostream>
using namespace std;
int z[10]={1,1,2,6,24,120,720,5040,40320,362880};
int main()
{  
    int i,a,b,c;
    for(i=0;i<=999;i++)
    {
    	a=i/100;
    	b=i/10%10;
    	c=i%10;
    	if(z[a]+z[b]+z[c]==i)
    	  cout<<i;
    }
    return 0;
}

Java :

public class Main {
	
	public static void main(String[] args) {
		for(int i=100;i<=999;i++) {
			int a=i/100;
			int b=i/10%10;
			int c=i%10;
			if(i==he(a)+he(b)+he(c)) {
				System.out.print(i+" ");
			}
		}
	}
	public static int he(int n) {
		if(n==0) {
			return 1;
		}else {
			return n*he(n-1);
		}
	}
}
