一道很水很水的题！！！！！！！！！！

#include<iostream>
using namespace std;
int main(){int num1,num2,i,k,j,sum,n;while(cin>>n){ while(n--){cin>>num1>>num2;if(num1>num2) {sum=num1;num1=num2;num2=sum;}k=0;for(i=num1;i<=num2;i++){   sum=0;for(j=1;j<=i/2;j++){if(i%j==0)sum+=j;}if(sum==i)k++;}cout<<k<<endl;}}return 0;
}
