Binary search recursion

WebWrite a C, C++ code to implement binary search program using recursion. What is Binary Search? Binary Search algorithm is used to search an element in a sorted array. Binary search works by comparing the value to the middle element of an array. If the value is found then index is returned otherwise the steps is repeated until the value is found. WebBinary search is an efficient algorithm for finding an item from a sorted list of items. It works by repeatedly dividing in half the portion of the list that could contain the item, until you've narrowed down the possible locations to just one. We used binary search in the guessing game in the introductory tutorial.
