using namespace std;

int main()
{
    int n,oldIntAll,oldIntOk,newIntAll,newIntOk;
    float oldE,newE;
    cout << "输入：";
    cin >> n;
    
    cin >> oldIntAll >> oldIntOk;
    oldE = oldIntOk * 1.0 / oldIntAll; //升级浮点除 
    
    for (int i=1;i<=(n-1);i++){
    	cin >> newIntAll >> newIntOk;
    	newE = newIntOk * 1.0 / newIntAll; //升级浮点除 
    	
    	if(newE-oldE > 0.05){
    		cout << "better" << endl;
		}else if(oldE - newE > 0.05){
			cout << "worse" << endl;
		}else{
			cout << "same" << endl;
		}
	}
	return 0;
}
//cout << "输入：";

结果：
