Why is it important to balance a Binary Search Tree?

Balancing a Binary Search Tree (BST) ensures optimal performance for operations like search, insert, and delete.

What happens if a BST is unbalanced?

An unbalanced BST can degrade to a linked list, leading to O(n) time complexity for operations instead of O(log n).

How can I balance a BST?

You can balance a BST using techniques like AVL trees or Red-Black trees, which maintain balance during insertions and deletions.

Are there any downsides to balancing a BST?

Yes, balancing a BST can add overhead in terms of time and space for maintaining balance during operations.

Can you give me an example of a balanced BST?

Sure! A balanced BST might look like this:

    4
   / \
  2   6
 / \ / \
1  3 5  7

This structure keeps operations efficient.
