        if(args.length == 1){
            int n=Integer.parseInt(args[0]);
            int a=0,b=1,c=0,i=0;
            while(i < n)
            {
                System.out.print(c +"\t");

                a=b;
                b=c;
    c=a+b;
                i++;
            }
        }
        else{
            System.out.println("You havent supplied the arguments: {Usage : java fibonacci 34 } to print the first 34
