_Recursive Worlds_
by Clifford A. Pickover


Example 1:

(a)

1 Factorial(X);
2     IF X=0 then Factorial=1
3     ELSE Factorial=X*Factorial(X-1)
4 END

(b)

1 Fibonacci(X)
2      IF N <= 1 then Fibonacci=1
3      ELSE Fibonacci=Fibonacci(N-1)+Fibonacci(N-2)
4 END

(c)

Fibonacci
    F[0]=1;F[1]=1;
    For ...
