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
Question
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
Solution
The steps that would require modification if the array were sorted in descending order are Step 3. In a descending order array, if the midpoint element is less than the target, you would update high to mid - 1 and continue the search in the left half. Conversely, if the midpoint element is greater than the target, you would update low to mid + 1 and continue the search in the right half.

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
