@[evvien](/user/297553) 您的 $N*10$ 和用两个scanner恕愚钝,无法理解.都用一个scanner就能过了啊
```java
public class Main {
public static void main(String[] args) {
int summ =0;
java.util.Scanner sc=new java.util.Scanner(System.in);
int N=sc.nextInt();
int liner[] = new int[N];
for (int i=0;i<N;i++) {
liner[i]=sc.nextInt();
}
sc.close();
for(int j=0;j<N;j++) {
for (int i=0;i<N-1;i++) {
if (liner[i]>liner[i+1]) {
int al = liner[i+1];
liner[i+1]=liner[i];
liner[i]=al;
summ +=1;
}
}
}
System.out.println(summ);
}
}
```
