Tribonacci Series

Write a program to write Tribonacci series.

import java.util.Scanner; 
public class TribonacciSeries
{
 public static void main(String[] args)
 {
   int x=-1,y=1,z=0;
   Scanner sc=new Scanner(System.in);            
   System.out.println("Enter a Number:-");    
   int n=sc.nextInt();
   System.out.println("The tribo series is:- ");
   triboSeries(n,z,x,y);
 }
 private static void triboSeries(int x,int f,int f1,int f2)
 {
   if(x==0)
   System.exit(0);
   System.out.print("  " + (f+f1+f2));
   triboSeries(--x,f1,f2,f+f1+f2);
 }
}


OUTPUT:

Enter a Number:-
10


The tribo series is:-
0  0  1  1  2  4  7  13  24  44



Enter a Number:-
8



The tribo series is:-

0  0  1  1  2  4  7  13
