Recursive : Python3
Output: Element is present at index 3 Time Complexity: O(log n) Auxiliary Space: O(logn) [NOTE: Recursion creates Call Stack] Iterative: Python3
Output: Element is present at index 3 Time Complexity: O(log n) Auxiliary Space: O(1) What is recursive binary search?Binary search is a recursive algorithm. The high level approach is that we examine the middle element of the list. The value of the middle element determines whether to terminate the algorithm (found the key), recursively search the left half of the list, or recursively search the right half of the list.
How do you write a recursive binary search in Python?def binary_search(my_list, low, high, elem): if high >= low: mid = (high + low) // 2 if my_list[mid] == elem: return mid elif my_list[mid] > elem: return binary_search(my_list, low, mid - 1, elem) else: return binary_search(my_list, mid + 1, high, elem) else: return -1 my_list = [ 1, 9, 11, 21, 34, 54, 67, 90 ] ...
What is recursive binary?In binary recursion, the function calls itself twice in each run. As a result, the calculation depends on two results from two different recursive calls to itself.
What is the recursive algorithm in Python?Recursive Functions in Python
A recursive function is a function defined in terms of itself via self-referential expressions. This means that the function will continue to call itself and repeat its behavior until some condition is met to return a result.
