Implement Binary Search algorithm using Divide and Conquer approach in python code example

Example: binary search python

# This is real binary search
# this algorithm works very good because it is recursive

def binarySearch(arr, min, max, x):
    if max >= min:
        i = int(min + (max - min) / 2) # average
        if arr[i] == x:
            return i
        elif arr[i] < x:
            return binarySearch(arr, i + 1, max, x)
        else:
            return binarySearch(arr, min, i - 1, x)
