why it give wrong answer?? only few test cases pased
import java.util.*;
public class Main {
public static void main(String args[]) {

Scanner kb=new Scanner(System.in);
int t=kb.nextInt();

 while(t-->0)
    {
	int n=kb.nextInt();

	int []zeroes=new int[n];
	int []ones=new int[n];

	zeroes[0]=1;
	ones[0]=1;

	for(int i=1;i<n;i++)
	   {
       zeroes[i]=zeroes[i-1] + ones[i-1];
	   ones[i]=zeroes[i-1];	
	   }	
	  
	  System.out.println(zeroes[n-1]+ones[n-1]);
	}

}

}

@abhishekg,

int []zeroes=new int[n];
int []ones=new int[n];

In the above arrays use long instead of int.
