Fibonacci using Recursive
public static void Main(string[] args)
{
    //Your code goes here
    for(int i=1; i<=7; i++)
    {
        Console.Write(fibonacci(i) + " ");
    }
}
In every single loop, we call fibonacci function that will adding number with recursive method.
public static int fibonacci(int angka)
{
    if(angka <= 1)
    {
        return angka;
    }
    else
    {
        return fibonacci(angka-1) + fibonacci (angka-2);
    }
}
