In Problem Solving With Algorithms And Data Structures Using Python by Miller and Ranum, two examples are given of a binary search algorithm. Both functions take a sorted list of numbers, alist, and a query, item, and return true if and only if item alist. The first version is iterative (using a loop within a single function call) and the second is recursive (calling itself with different arguments). Both versions can be found on the last page of this problem set. Let n = len(alist).

Explain how you might fix the recursive version so that it has the same asymptotic running time as the iterative version (but is still recursive).

Iterative Version: def binarySearch(alist, item): first = 0 last = len(alist)-1 found = False while first
