HDU 1406 注意输入判断num1 和 num2的大小

#include <iostream>using namespace std;bool isok(int a){int sum = 0;for(int i = 1; i < a; i++)if(a % i == 0)sum += i;if(sum == a)return true;return false;}int main(){int t; cin >> t;int a, b;while(t--){cin >> a >> b;if(a > b)swap(a, b);int cnt  = 0;for(int i = a; i <=b; i++){if(isok(i))cnt++;}cout << cnt << endl;}return 0;}
