Solution

It seems like you're describing a binary search algorithm. Here's a step-by-step breakdown:

  1. Initialize your search space to be the entire array.
  2. Find the middle element of your search space.
  3. If the middle element matches your target, stop; you've found your target.
  4. If the target is less than the middle element, narrow your search to the left half of your current search space.
  5. If the target is greater than the middle element, narrow your search to the right half of your current search space.
  6. Repeat steps 2-5 until you either find your target or exhaust your search space. If you've exhausted your search space, the target is not in the array.

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?

What is the worst-case scenario for binary search?a.The target element is in the middle of the array.b.The target element is the first element of the array.c.The target element is not present in the array.d.The target element is the last element of the array.Clear my choice

Given a sorted array A of size N, along with an integer target K, implement Binary Search to find the target K in the given array.Input FormatThe first line of input contains an integer N - the size of an array and target K. The second line contains the elements of the array.Output FormatFor each iteration of Binary Search, print the values of low, high, and mid. At the end, if the target K is found in the array, print "True" otherwise, print "False".Constraints1 <= N <= 201 <= A[i] <= 103ExampleInput 19 121 4 6 7 10 11 12 20 23Output 10 8 45 8 6TrueInput 210 213 5 8 11 15 17 19 23 26 30Output 20 9 45 9 75 6 56 6 6False
