Getting NZEC in java

import java.util.Scanner;
class Main
{
public static void main(String args[])
{
Scanner sc=new Scanner(System.in);
int t=0;
Main obj=new Main();
t=sc.nextInt();
String in[]=new String[t];
for(int i=0;i<t;i++)
try{ in[i]=sc.next();
}catch(Exception e){}
for(int i=0;i<t;i++)
obj.show(in[i]);

	}
	public void show(String in)
	{

		int top=0,current=0;

		System.out.println((fact(in.length())/den)%1000000007);
	}
	
	int fact(int n)
	{

	}
}

I’m getting NZEC and I can’t figure out the problem
Code runs fine on my PC

Are you reading S from input ?

what do you mean by that?
can you point to the exact line please

I finally did it in java :slight_smile:
