We can get faster fib just returning two values

How do you make fib fast?
I don't recomend using memoization because it require waste memory.
I recommend returning two values.


  1. A simple method that is a direct recursive implementation mathematical recurrence relation given. We can observe that this implementation does a lot of repeated work see the following recursion tree. So this is a bad implementation Write My Essay For Me Cheap for nth Fibonacci number. We can optimize the space used in method 2 by storing the previous two numbers only because that is all we need to get the next Fibonacci number in series.

  2. Questionnaire writing tips in most cases are dictated by common sense and basic knowledge of human psychology. Preparation is as important in the questionnaire, as it is in any other form of writing
