只—有—四—10—分—的—代—码

#include <iostream>
using namespace std;
int main(){
	int saved = 0,sum = 0;
	for(int i = 1;i<=12;i++){
		sum += 300;
		int budget;cin>>budget;
		if(sum < budget){
			cout<<"-"<<i;
    		return 0;
	    }
	    sum -= budget;
    	saved += sum / 100;
    	sum = sum % 100;
    }
    saved += (saved / 5);
    sum += saved;
    cout<<sum;
    return 0;
}

测试点2都过不去，我是真蔡鸡
