@[User_BDAD](/user/1321318) java的标准输入输出较慢，建议使用快读快写加速一下
快读模板
```java
class Read {
StreamTokenizer st = new StreamTokenizer(new BufferedReader(new InputStreamReader(System.in)));
public int nextInt() throws Exception {
st.nextToken();
return (int) st.nval;
}
}
```

@[yahuac](/user/997832) ok我试试

@[User_BDAD](/user/1321318) 我也是同样的情况，用快读也超0.2秒，你的可以过吗？

@[User_BDAD](/user/1321318) 还可以加个快写
```java
static PrintWriter pw = new PrintWriter(new BufferedOutputStream(System.out));
pw.println();
pw.close();
```

我是这样写的，也超时了
```java
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.io.StreamTokenizer;
import java.util.Scanner;
public class Main {
static StreamTokenizer in = new StreamTokenizer(new BufferedReader(new InputStreamReader(System.in)));
static int nextInt() throws Exception{
in.nextToken();
return (int)in.nval;
}
static int n,m;
static PrintWriter out = new PrintWriter(System.out);
public static void main(String[] args)throws Exception {
int n=nextInt(),m=nextInt();
int[][] a=new int [n+2][n+2];
for(int i=0;i<m;i++) {
int x1=nextInt(),y1=nextInt(),x2=nextInt(),y2=nextInt();
a[x1][y1]+=1;
a[x2+1][y2+1]+=1;
a[x2+1][y1]-=1;
a[x1][y2+1]-=1;
}
for(int i=1;i<=n;i++) {
for(int j=1;j<=n;j++) {
a[i][j]+=a[i][j-1]+a[i-1][j]-a[i-1][j-1];
out.print(a[i][j]+" ");
out.flush();
}
out.println();
out.flush();
}
}
}
```
