冒泡过程这样写试试
```cpp
for(int i=1;i<=n;i++){
for(int j=i+1;j<=n;j++){
if(a[i]>a[j]){
int tmp=a[i];
a[i]=a[j];
a[j]=tmp;
ans++;
}
}
}
```

```
#include<bits/stdc++.h>
using namespace std;
int main(){
int n,a[10000],ans=0;
cin>>n;
for(int i=0;i<n;i++){
cin>>a[i];
}
for(int i=0;i<n;i++){
for(int j=0;j<i;j++){
if(a[i]<a[j]){
ans++;
}
}
}
cout<<ans;
}
```
