Small factorials wrong answer

[Reyner]

Who is the error?:

import java.util.*;
public class Main
{
  public static int factorial( int n )
  {
        if( n<=1)
           return 1;
        else
           return n*factorial( n-1);
  }
  public static void main(String args[])
         {     
               Scanner s=new Scanner(System.in);
               int n;int a;
               if((n=s.nextInt())>=1&&n<=100){
               int i=1;
               while(i++<=n)
               {
                 if((a=s.nextInt())>=1&&n<=100)
                 System.out.println(factorial(a));
                }
               }
          }
}

There's only 100 test cases to choose from.. try the right one and the error is obvious.
