How do I implement a B-tree?

Can you explain what a B-tree is?

A B-tree is a self-balancing tree data structure that maintains sorted data and allows for efficient insertion, deletion, and search operations.

How do I implement a B-tree in Python?

To implement a B-tree in Python, you need to define a BTree class with methods for insertion, deletion, and searching. Would you like a code example?

Yes, please provide a code example.

Here's a simple implementation of a B-tree in Python:

class BTreeNode:
    def __init__(self, t, leaf=False):
        self.t = t  # Minimum degree
        self.leaf = leaf  # True if leaf node
        self.keys = []  # List of keys
        self.children = []  # List of child pointers

class BTree:
    def __init__(self, t):
        self.root = BTreeNode(t, True)
        self.t = t

    def insert(self, key):
        # Implementation of insert method
        pass

    def delete(self, key):
        # Implementation of delete method
        pass

    def search(self, key):
        # Implementation of search method
        pass

This is just a starting point!

What are the advantages of using a B-tree?

B-trees are efficient for disk-based storage systems, as they minimize disk reads and writes. They also maintain balance, ensuring logarithmic time complexity for operations.
