解题思路:





注意事项:





参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int N = sc.nextInt();

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

int b = 0;

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

if(i%j==0)

b+=j;

}

if (i==b){

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

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

if(i%m==0)

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

}

System.out.println();

}

}

}

}
