### My issue

I am practicing this problem and there is no contest that is currently running on

so how is it stopping me from saying that my time is over for this contest

## It is just a practice problem

### My code

```
/* package codechef; // don't place package name! */
import java.util.*;
import java.lang.*;
import java.io.*;
/* Name of the class has to be "Main" only if the class is public. */
class Codechef
{
public static void SieveOfEratosthenes(int m,int n){
boolean[] prime = new boolean[n+1];
Arrays.fill(prime,true);
prime[1] = false;
for(int i = 2 ; i*i<=n;i++){
if(prime[i]){
for(int j = i*i ;j<=n;j+=i)
prime[j] = false;
}
}
for(int i = m;i<=n;i++){
if(prime[i])
System.out.println(i);
}
}
public static void main (String[] args) throws java.lang.Exception
{
// your code goes here
Scanner s = new Scanner(System.in);
int t = s.nextInt();
while(t-->0){
int m = s.nextInt();
int n = s.nextInt();
SieveOfEratosthenes(m,n);
}
}
}
```
