```cpp
Temp=a[j-1];
a[j-1]=a[j];
a[j-1]=Temp;
```
这里错了。

```cpp
#include <iostream>
using namespace std;
int n, sum;
int main()
{
cin >> n;
int a[n+1];
for (int i = 1; i <= n; i++) cin >> a[i];
for (int i = 1; i <= n; i++)
for (int j = 1; j <= i; j++)
if (a[j] > a[i])
sum++;
cout << sum;
return 0;
}
```

```cpp
if ( a[j-1]>a[j] ) {
Temp=a[j-1];
a[j-1]=a[j];
a[j-1]=Temp;
cnt++;
}
```
这错了，正解：
```cpp
if ( a[j-1]>a[i-1] ) {
Temp=a[j-1];
a[j-1]=a[j];
a[j-1]=Temp;
cnt++;
}
```

@[czh02232037](/user/805642) 第二个不对喔。第一个不是很理解为什么要a[i]和a[j]比，谢谢

@[AC_CSP](/user/481527) 师兄你好，我调试发现没问题呀，我按照排序来写的！好难

@[czh02232037](/user/805642) 师兄你的思路我明白了，我的思路哪里错了呀？望指教

@[AC_CSP](/user/481527) 懂了懂了，我把那段代码删去就ok了，谢谢大佬
