@[天南星魔芋](/user/399239) 改了 这次直接RE
```cpp

int sum = 0;
for(int i = 0; i < a.size(); i++) sum+=a[i];
return sum;
}
int sum_b(){
int sum = 0;
for(int i = 0; i < b.size(); i++) sum+=b[i];
return sum;
}
int main() {
cin >> n;
int x;
for(int i = 0; i < n/2; i++){
cin >> x;
a.push_back(x);
}
for(int i = n/2;i<n;i++){
cin >> x;
b.push_back(x);
}
int minn = abs(sum_a()-sum_b());
for(int i = 0; i < a.size(); i++){
for(int j = 0; j < b.size(); j++){
if(abs((sum_a()+a[i])-(sum_b()-b[j]))<=minn){
a.push_back(b[j]);
b.erase(b.begin()+j-1);

i = j = 0;
}
}
}
cout << sum_a() << " " << sum_b() << endl;
return 0;

@[天南星魔芋](/user/399239) 那为什么还是WA?
是不是第31行写挂了
by AndyChen2005121 @ 2021-05-04 16:59:41
@[AndyChen2005121](/user/152652)
不是，是因为贪心贪错了吧？
by 天南星魔芋 @ 2021-05-04 17:05:26
比如
```
4
1 2 3 4
```
和
```
4
1 2 4 3
```
程序答案不一样
by 天南星魔芋 @ 2021-05-04 17:07:23
@[天南星魔芋](/user/399239) 对于你这个hack数据，我把第31行改成
```cpp
if(abs((sum_a()+a[i])-(sum_b()-b[j]))<minn)
```
答案就一样了， 但还是WA
