WebI know how to code for factorials using both iterative and recursive (e.g. n * factorial(n-1) for e.g.). I read in a textbook (without been given any further explanations) that there is an even more efficient way of coding for factorials by dividing them in half recursively. I understand why that may be the case. WebFeb 4, 2024 · Your understanding of how recursive code maps to a recurrence is flawed, and hence the recurrence you've written is "the cost of T(n) is n lots of T(n-1)", which clearly isn't the case in the recursion.
