What is the initial step in executing a binary search on a sorted array?*1 pointA. Traverse the entire array from start to end.B. Compare the target value to the middle element.C. Sort the array in ascending order.D. Calculate the average value of the elements.

Program to demonstrate the use of Binary Search to search a given element in a sorted array in ascending order.

The following steps are required to implement the binary search for an array sorted in ascending order.1) 1)Initialize Pointers: - Set two pointers, `low` and `high`, initially pointing to the start and end of the array, respectively. 2) Calculate Midpoint: - Calculate the midpoint index using the formula `mid = (low + high) // 2`. 3) Compare Midpoint Element: - Compare the element at the midpoint with the target element you are searching for: - If the midpoint element is equal to the target, the search is successful, and you can return the index. - If the midpoint element is less than the target, update `low` to `mid + 1` and continue the search in the right half. - If the midpoint element is greater than the target, update `high` to `mid - 1` and continue the search in the left half. 4) Repeat: - Repeat steps 3-4 until the `low` pointer is greater than the `high` pointer. This means the search range has become empty. 5) Return Result: - If the target element is found, return its index. If the target is not found, return a sentinel value (e.g.,-1) to indicate that the element is not in the array.Which steps would require modification if the array were sorted in descending order? Step 2 Step 4 Steps 2 and 4 No modification in steps

Suppose there are 11 items in sorted order in an array. How many searches are required on average, if binary search is employed and all searches are successful in finding the item?

Write a function that performs binary search on a sorted array.

Alex wants to create a program to search a target value in a sorted array. The program should input the array size and elements, as well as the target value. Utilizing binary search, it should determine if the target is present, and if so, provide the index. If not, display a message indicating its absence.Assist Alex in completing the program efficiently.Input format :The first line of input consists of an integer N, representing the size of the sorted array.The second line consists of N space-separated integers, the elements of the sorted array in ascending order.The third line consists of an integer target, the value to search for in the array.Output format :If the target is present in the array, print "The target value X is present at index Y", where X is the target element and Y is the index position (index starts from 0).If the target is not present, print "The target value X is not present in the array", where X is the target element.
