WebBinary Search Algorithm in C++ 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 recursive call on the second half of the array. WebBinary Search Algorithm – Iterative and Recursive Implementation Given a sorted array of n integers and a target value, determine if the target exists in the array in logarithmic time using the binary search algorithm. If target exists in the array, print the index of it. For example, Input: nums [] = [2, 3, 5, 7, 9] target = 7
