How to code Binary Search Algorithm using Recursion in Java?

WebThe idea is to use binary search which is a Divide and Conquer algorithm. Like all divide-and-conquer algorithms, binary search first divides a large array into two smaller subarrays and then recursively (or iteratively) operate the subarrays. But instead of working on both subarrays, it discards one subarray and continues on the second ... WebThe recursive method of binary search follows the divide and conquer approach.
