import java.util.Scanner;

public class End_Count {

    public static void main(String[] args) {
        System.out.println("多少范围内的完数？请输入：");
        Scanner input = new Scanner(System.in);
        int n = input.nextInt();
        int i,j,k;
        for(i = 1; i<=n; i++) {
            k =0;
            
            for(j =1; j<=i-1; j++)
                if(i%j == 0)
                    k+=j;
            if(k == i)
                System.out.print(i + " ");

The end!");
