打扰了
自己debug出来了quq```cpp
#include<iostream>
using namespace std;
int main()
{
int N = 0;
cin >> N;
int arr[10000];
for (int a = 0;a <= N - 1;a++) {
cin >> arr[a];
}
int i = 0;
int j = 9999;
int sum = 0;
int n = 0;
n = N - 1;
while (arr[i] != 0 && arr[n] != 0 && i < n)
{
while (arr[i] != 0 && arr[n] != 0 && i < n)
{
if (arr[i] > arr[n]) {
sum++;
}
i++;
}
i = 0;
n--;
}
cout << sum << endl;
}
```
