WebApproach 1: Iterative Binary Searching Operation In this method, we'll iterate through the entire list, repeating a series of instructions. We'll keep looking for the middle value until we've found it. Let's have a look at the Algorithm followed by code for better understanding: Binary Search Algorithm WebIterative method Recursive method The recursive method of binary search follows the divide and conquer approach. Let the elements of array are - Let the element to search is, K = 56 We have to use the below formula to calculate the mid of the array - mid = (beg + end)/2 So, in the given array - beg = 0 end = 8 mid = (0 + 8)/2 = 4.
