Remove BST keys outside the given range in Java language

Remove BST keys outside the given range in Java language 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 BST keys outside the given range in Java language.

From the example next to this theory: Remove BST keys outside the given range in Java language — bST invariant: left < node < right — enables log-time search when balanced.

Trap — unbalanced BST becoming a list. Fix that before you talk about advanced DSA.

Viva: what is Remove BST keys outside the given range in Java language? Then show left < root < right. Then name the trap.

Exam tip

What is Remove BST keys outside the given range in Java language? Show this: left < root < right. Trap: unbalanced BST becoming a list.

Example

class Node:
    def __init__(self, val):
        self.val = val
        self.left = None
        self.right = None

def insert(root, val):
    if root is None:
        return Node(val)
    if val < root.val:
        root.left = insert(root.left, val)
    elif val > root.val:
        root.right = insert(root.right, val)
    return root

root = None
for v in [5, 2, 7, 1]:
    root = insert(root, v)
print(root.val, root.left.val, root.right.val)

Remove BST keys outside the given range in Java language — bST invariant: left < node < right — enables log-time search when balanced.
