Binary search recursive c++

WebDrawbacks of Binary search. Binary search works only on sorted data. Recursion in Binary Search. The concept of recursion is to call the same function repeatedly within itself. There is a condition when this recursion stops. At each step of Binary Search, we reduce the potential size of the array by half where the target element can be found. WebBinary Search (Recursive) Given an integer sorted array (sorted in increasing order) and an element x, find the x in given array using binary search. Return the index of x. Return -1 if x is not present in the given array. Note : If given array size is even, take first mid. Input format : Line 1 : Array size
