Find Clockwise Array in Binary Search Tree

Don’t start Find Clockwise Array in Binary Search Tree with jargon. Start with folder on disk. That is the whole point.

Do Find Clockwise Array in Binary Search Tree once by hand. left < root < right. Change one input. Say the new result out loud.

Find Clockwise Array in Binary Search Tree exists so Farhan can keep folder on disk correct in a file explorer.

Farhan ships Find Clockwise Array in Binary Search Tree in a file explorer. That is the use case worth saying.

Find Clockwise Array in Binary Search Tree trap: unbalanced BST becoming a list. Farhan loses marks for that every viva.

After Find Clockwise Array in Binary Search Tree, Farhan should still remember unbalanced BST becoming a list.

Viva for Find Clockwise Array in Binary Search Tree: what it is → left < root < right → the mistake (unbalanced BST becoming a list).

Exam tip

Board: folder on disk. Dry-run Find Clockwise Array in Binary Search Tree. Name the trap: unbalanced BST becoming a list.

Example

def binary_search(arr, target):
    lo, hi = 0, len(arr) - 1
    while lo <= hi:
        mid = (lo + hi) // 2
        if arr[mid] == target:
            return mid
        if arr[mid] < target:
            lo = mid + 1
        else:
            hi = mid - 1
    return -1

print(binary_search([1, 3, 5, 7, 9], 7))

Find Clockwise Array in Binary Search Tree — binary search halves a sorted array each step — O(log n).
