解题思路:





注意事项:





参考代码:

import java.util.Scanner;

public class C1017 {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

while(sc.hasNext()){

int n = sc.nextInt();

for(int i = 0; i <= n; i++){

print(i);

}

}

sc.close();

}

public static void print(int x){

int sum  = 0;

for(int i = 1; i < x; i++){

if(x%i == 0){

sum += i;

}

}

if(sum == x && x != 0){

System.out.print(x + " its factors are ");

for(int i = 1; i < x; i++){

if(x%i == 0){

System.out.print(i + " ");

}

}

System.out.println();

}

}

}
