WebHere’s how you do that by threading it through each recursive call (i.e. passing the updated current state to each recursive call as arguments): def sum_recursive ( current_number , accumulated_sum ): # Base case # Return the final state if current_number == 11 : return accumulated_sum # Recursive case # Thread the state through the recursive ... WebMay 12, 2014 · This dependency makes it hard to do it in parallel if you start every time with 1 and 1. However, if you need to do Fibonacci calculations more often, it could be a good idea to store (or cache) pre-calculated results in order to avoid all calculations up to that point. The concept behind is quite similar to rainbow tables.
