What are binary search trees in Python?

Binary Search Trees (BST) are data structures that store elements in a sorted manner, allowing for efficient search, insert, and delete operations.

How do I implement a binary search tree in Python?

You can implement a BST by creating a Node class and a BST class that manages the nodes. Would you like a code example?

Yes, please provide a code example.

Here's a simple implementation:

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

class BST:
    def insert(self, root, key):
        if root is None:
            return Node(key)
        else:
            if root.val < key:
                root.right = self.insert(root.right, key)
            else:
                root.left = self.insert(root.left, key)
        return root

What are the advantages of using a binary search tree?

BSTs provide efficient searching, insertion, and deletion operations, typically in O(log n) time, making them suitable for dynamic datasets.
