还是不对
by __Tonycyt__ @ 2024-02-09 09:55:26
首先36行改成 cout << "+" << a[n]; 才能过样例1
by __Tonycyt__ @ 2024-02-09 09:55:39
然后我再找找

还是20分
by __Tonycyt__ @ 2024-02-09 09:58:25
然后35行 if (a[n]>0||a[n]<0) 改成 if (a[n]!=0) 会运行快一些（!= 就是不等于）

@Cuimenghao 我知道，我在找了
by __Tonycyt__ @ 2024-02-09 09:59:22
我下载个数据点看一眼吧
by __Tonycyt__ @ 2024-02-09 10:01:14
读入之后加一个特判。
if (n == 0){
cout << a[0];
return 0;
}by __Tonycyt__ @ 2024-02-09 10:02:47
这样能多AC一个点（虽然这个点0分，但是你不AC这个点就算你AC其他所有点系统也算你不通过）

OK
