Implement the random Fibonacci sequence
The random Fibonacci sequence is defined as follows:
$$
f_n =
\begin{cases}
f_{n-1}+f_{n-2} \text{ with probability } 1/2 \\
f_{n-1}-f_{n-2} \text{ with probability } 1/2 \\
\end{cases}
$$
$$
f_1 = f_2 = 1
$$
i.e. whether the next term is the sum or differ...
