WebBinary Search Algorithm in Python using Recursive Approach a) Take an array, initial index, size, and search key. b) Find the middle term. c) if middle term == search key then return index. d) if middle term > search key then apply recursive call on the first half of the array. e) else apply a recursive call on the second half of the array. WebThere are two ways to implement Binary Search are-. 1. Iterative Approach – In iterative approach the track record of the list is kept manually. This search completes when the search number is found or the two pointers (first and last) are met.
