1 Fibonacci Fibonacci series 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 Definition:
fib(n) = fib(n-1) + fib(n-2) en.wikipedia.org/wiki/Fibonacci_number

3 Recursion and Efficiency
Fib(6) Fib(4) The recursive form, however elegant, may be much less efficient The number of redundant calls grow exponentially!

4 Efficient Recursive Fibonacci
Pass the values that were already calculated to the recursive function This technique is called Memoization How would we keep the values that were already calculated?
