Difference between B-Tree and Binary Tree

If you can teach Difference between B-Tree and Binary Tree using folder on disk, you know it. If you only know the heading, you don’t.

Difference between B-Tree and Binary Tree on the board: left < root < right. Then say what folder on disk looks like after.

Difference between B-Tree and Binary Tree exists so Asha can keep folder on disk correct in a file explorer.

Asha ships Difference between B-Tree and Binary Tree in a file explorer. That is the use case worth saying.

Don’t do this with Difference between B-Tree and Binary Tree: unbalanced BST becoming a list. Interviewers spot it in ten seconds.

Place Difference between B-Tree and Binary Tree next to nearby DSA work — left < root < right is the link.

Viva for Difference between B-Tree and Binary Tree: what it is → left < root < right → the mistake (unbalanced BST becoming a list).

Exam tip

Board: folder on disk. Dry-run Difference between B-Tree and Binary Tree. Name the trap: unbalanced BST becoming a list.

Example

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

def inorder(n):
    if not n:
        return []
    return inorder(n.left) + [n.val] + inorder(n.right)

root = Node(2, Node(1), Node(3))
print(inorder(root))

Difference between B-Tree and Binary Tree — inorder walks left → node → right (sorted order for a BST).
