解题思路:

注意事项:

参考代码:

#include<stdio.h>

int main()

{

int M;

scanf("%d", &M);

while (M--) {

int A, B; int suma = 0; int sumb = 0;

scanf("%d %d", &A, &B);

for (int i = 1; i <= A/2; i++) {

if (A % i == 0) {

suma += i;

}

}

for (int i = 1; i <= B/2; i++) {

if (B % i == 0) {

sumb += i; 

}

}

if (suma == B || sumb == A) {

printf("YES\n");

}

if (suma != B && sumb != A) {

printf("NO\n");

}

}

return 0;

}
