👉 In computer science, a recurvoternate is an algorithm that takes a list of numbers and returns a new list where each element in the original list is equal to the sum of all elements in the previous sublists. The recurrence relation for this algorithm is: ``` T(n) = 2T(n/2) + O(1) ``` where `O(1)` represents constant time complexity and `n` is the number of elements in the list. In other
