蓝桥杯算法训练VIP-友好数-题解（Java代码）

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 scanner=new Scanner(System.in);

int m=scanner.nextInt();

int n=scanner.nextInt();

int sum1= pd1(m);

int sum2=pd1(n);

if(sum1==n&&sum2==m)

System.out.print("yes");

else

System.out.print("no");

}

private static int pd1(int n) {

// TODO Auto-generated method stub

int sum=1;

for(int i=2;i<n;i++) {

if(n%i==0) {

sum+=i;

}

}

return sum;

}

}
