Remove all leaf nodes from the binary search tree — DSA Technical Interview Questions & Answers

Remove all leaf nodes from the binary search tree

Remove all leaf nodes from the binary search tree

  • Remove all leaf nodes from the binary search tree is a DSA topic. In plain words you use it for folder on disk in a file explorer. Don’t start with a slogan — start with that picture.
  • Smallest example: left < root < right. Type it, run it, and say what you see. If you can do that from memory, you know Remove all leaf nodes from the binary search tree.
  • From the example next to this theory: Remove all leaf nodes from the binary search tree — binary search halves a sorted array each step — O(log n).
  • Trap: unbalanced BST becoming a list. Fix that before you talk about advanced DSA.
  • Viva: what is Remove all leaf nodes from the binary search tree? Then show left < root < right. Then name the trap.

Technical Interview Tip: What is Remove all leaf nodes from the binary search tree? Show this: left < root < right. Trap: unbalanced BST becoming a list.

Code Examples for Remove all leaf nodes from the binary search tree

Remove all leaf nodes from the binary search tree — working 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))
