One can do a (tiny) bit of math to rewrite your function: Now notice, that if you consider a matrix F_{ixn}, to compute F(i,n) we just need to add the elements of the previous column. After solving Fn=Fn-1+Fn-2 expression you will get a formula by which you can calculate nth term of Fibonacci series. The following suggestions aren't really about efficiency (if they change the efficiency of your code, the difference will be immeasurably small), but they might make your code a little cleaner. $$\frac{2}{(1+x)^3}=2-6x+12x^2-20x^3+30x^4-42x^5+\dots,\qquad |x|<1.$$ Finally, by multiplying $\frac{1}{2}$ to both sides, we get Time Complexity: O(log N)Auxiliary Space: O(log N), if we consider the function call stack size, otherwise O(1).

Given an integer as an input, the objective is to find the Fibonacci series until the number input as the Nth term. We can make this work for us, and achieve understandable code by keeping functions short - in most cases 5 or less lines. I try to avoid negative terms in these conditions e.g. Rather than include the n/2 loop in both the Fibonacci and prime code, I'd make it external and turn these two programs into simpler, infinite generators that are easier to debug: This is my first post for suggesting improvements so I may be way off the mark but I think you should.
